@SlotHits777 Год назад

Those are unsuitable for pairing with the speaker for rear/side surround channels. Chasis are way too large. Where as the Fosi fits nicely on top of the speaker, completely wireless other than power cable for the amp. The Fosi is great for SR channels, just dont use for LCR channels.

@robertdowell9493 3 месяца назад

I’m a professional sound engineer. Amplifiers only need to do one thing: take a small signal and without adding or subtracting anything from the signal, make it much larger. These little amps do this very well indeed, often much better than pretty much any older domestic audio kit - at any price. Domestic audio is more often garbage than not, again, at any price. Unless you’re listening in an acoustically treated monitoring room on the flattest of studio monitors, you’re not going to find anything to fault with these things. I say buy them enjoy your music without worrying about the cost and obsessing about inaudible sonic artefacts.

99% of the time i agree with your reviews. Today not so much. I own fortes IVs, Heresy IVs, Quartets and original 770s along with Decware Sarah, Willsenton R8 Audiolab 6000a and pioneer 980 and a Fosi a20 pro. I paired the Fosi with a couple different dacs and was surprised how good it is, For the money. I would recommend it to people who don't have a large budget or just want to see if they want to get into the hobby. The cambrdge is a good amp but if you get into the hobby at all you will out grow it very quickly and its really limited by power. Fosi is closer to 35-40wpc out of box. So personaly i would rather have the Fosi powering speakers in my garage like mine is used for or on a desk than the cambridge axa25 at 3 times the price and size. Always appreciate your opinions whether i agree or not. 😊

@jimfarrell4635 Год назад

Pretty much my experience exactly, and the Fosi allows you to roll the op amps which is fun. Anything which reduces the price of entry to this hobby has got to be a good thing, and it gives old timers like me something to play with which doesn't make me feel too guilty for buying yet another piece of kit.

@johnboard7770 Год назад

Scott I concur with everything you said. I own vintage La Scalas, Heresy II’s and a vintage Pioneer 780. Sounds like we have similar tastes. I am wondering how you are liking the Sarah amp. I am soon to move to page one of the decware waiting list for a zen but can upgrade to the Sarah. I currently have a Schiit Freya plus and mono Aegirs as my main system but am getting long in the tooth and would like to assemble my forever system. Are you loving the Sarah? How does she compare to the Willenston? Did you spring for the Western Electric tubes? If so, how did they perform?

@broom150 Год назад

@John Board The Willsenton is my work horse that I use daily. It's has el34 mallards and tung sol front end use it everyday and I love it. But the Sarah is Special and is the only piece i own that wont leave my collection. I do not have the WH 300B so cant speak to those.

I recently bought the Aiyima A07 & paired it with the Douk Audio P2 tube buffer, which added 3 way tone controls, remote control, Bluetooth, it really fleshed out the sound of the aiyima, drives my Dali floorstanders with ease, no weird whining noise, just silence, it's usually the cheap power bricks that are the weak link in these budget class d amps, i owned the Cambridge audio axa35 for a short time but found it thin, bright, with terrible tone controls, this pre, power combo for £120 sounds way better to me, the Aiyima A07 has been reviewed, modded, tested so much that I'm sure that if it was a speaker destroyer, it would have been flagged up by now! Just my honest opinion 👍

I use the B50 in my small living room set up. Although it is not a fantastic amp, it works just fine in this scenario and I love the fact that it has a ARC and CEC. I mainly use the system for working out and watching ball games along with some occasional airplay audio. It certainly doesn’t sound as good as my Emotiva BasX amps or even those built into my Denon receivers, but I think it is fantastic for what it offers at $140.

These amps are not limited to near field, that’s silly. Power is power, and the Ayima 07 can easily drive floor standing speakers in a large room. Plus, measurements don’t lie and the 07 has excellent measurements.

@williambeckner1368 Год назад

As a college student, I started out by getting a desk setup with a Schiit DAC and Fosi amp to run a cheap pair of Elacs I picked up used (only source is my computer at this point), and can confirm that while it was functional, it definitely was not the best option. While I'd still say the Schiit DAC has been great, and the Elacs have been great for the price ($60), I saved up and got a used Emotiva amp for $120 and it is WORLDS better than the Fosi. In the living room, my roommates and I are running a pair of vintage Kenwood floorstanders with a paradigm center and sub (admittedly had to replace some resistors on the sub) along with a couple cheap surrounds through an old Harmon Kardon receiver. All in all, that movie setup was about $170, and while not perfect, it is great for the price. I say all this to say I'd encourage anyone looking to save money to look into buying used before getting worse equipment. There are often many great deals to be had and better equipment for the money, no matter the application.

@user-qn9zb4tk7i Год назад

I bought the Aiyima a07, Fiio k5 dac, Elac db62 and Elac 130 sub for Christmas. Complete system with stands and wires for $600. It sounds great! For me, it wasn’t about the money, it was about dipping my toe back into the hobby. Before I bought this little system, I had a wish list $8000 long! Didn’t want to get stuck with it if I wasn’t going to use it. Because this has been such a good experience, I’m back to researching my next system to include high quality components. In my mind, this industry would never get my future money if cheap, borderline good quality components were not available.

@@nuggyfresh6430 They have to project sound about 3 feet. The sound is very clear at that range. There is no way a more expensive amp could sound better to my ear. At this point, the speakers are likely the limiting factor, but I am out of money. And perfectly satisfied. I saw a McLaren at the grocery store today. My Kia was the better tool for picking up groceries. I could list 50 instances in 30 minutes where the more expensive option is wasted money. Starting with the Concorde. My use of the word niche was intended to indicate that there are other cases that call for better equipment. But not this case.

@jseals811 Год назад

I've had great luck with these amps. They are fun to tinker with. I have used an A07 in my wood working workshop, so being enclosed and cheap is of great benefit. I run a JBL control sb-2 (a passive sub that accepts a full range stereo input and has a low pass to itself and high pass to the mains) and a pair of JBL arena 170 towers. While I haven't taken an SPL reading I can drive it to paint can rattling levels that compete with the table saw. I have tried several different class D amps and some are better than others but they have all been reliable and low noise. I package them with speakers that I have repaired and/or veneered and give to friends as sound bar alternatives or desktop systems. It's great because I tend to accumulate gear and I try to keep the outgoing and incoming equal. I use a Rotel and B and Ws on my main listening system but my scrappy workshop system puts a bigger smile on my face jamming out after a long day covered in saw dust.

I too have an A07. I initially hooked it up to my Tannoy XT-8F towers, which were driven just fine. My purpose for getting the amp though, was to drive the two Canton Atelier 750s in my (open) dining room at typically low volume (since I maxed out the amps in my Marantz sr6015). I find it perfectly capable to fulfil this task, but I'm not picky.

Thanks for the review! My Fosi TB10D is super quiet, with none of the high frequency noise you mentioned in your video. It is also surprisingly loud and powerful sounding with the included power supply. It sounds pretty darn good for a cheap chip amp. I also have a 1985 Yamaha A-1020 which I recently spent $ getting it repaired because all the newer amps I tried, such as the Cambridge AXA35, Rotel A11 Tribute and Yamaha AS501 didn`t come close enough to the sound quality of my Auto Class A 125 W/Ch Yamaha amp that was recently repaired. The Fosi TB10D gives me about 85% of the sound quality of my Yamaha. The Fosi TB10D is surprisingly good sounding for a cheap amp, and I use it daily to save wear and tear on my A1020, which I use every few days to get a great fix of high fidelity. Yes, the Fosi TB10D sounds like it is missing 15% of the sound quality compared to my Yamaha A1020, but it is still quite good for what it is, and I can leave it on all the time without heating up the house. I feel it would be a super good starter amp for someone...

@NeilBlanchard Год назад

Class D amps use PWM (pulse width modulation) to generate an amplified signal - and because the PWM frequency is essentially *high frequency noise* it must have a low pass filter to remove it from the sound you hear out of the speakers. This means that *some* of that noise is not able to be filtered out *and* that there are phase shifts happening because of the filter. Better Class D designs use a (much?) higher PWM frequency - which makes it *much* easier/better to filter out the noise. And there is less phase shift because the filters are set higher and have more effect with a lower slope filter.

Exactly. The quality of the low pass filter is everything with class D design. If you have the room, you are much better off with a cheap 20 year old receiver from a thrift shop. I've currently got two two optimus, an HK, Denon, Onkyo, Yamaha, and two Sony receivers. I've got several tower speakers and bookshelves and have interchanged all of them.

Appreciate the video and you are right about the Cambridge. I bought the Fosi 20a pro just out of curiosity and have not been disappointed. It powers my 93db sensitive Zingali speakers and my Kef LS50s to high volumes in a large room and the audio was really pretty enjoyable. My normal amps are, respectively 25 and 60 times more expensive, and I won't be getting rid of them any time soon but the wee amp is fun. The brightness and sibilance is noticeable but not too bad and disappeared after swapping the op amps to Burson Audio ( though I had to modify the casework to fit them in ). Of course that bumps the cost up if you don't have op amps lying around like I did.

I have the Aiyima A07, SMSL A100 and AO200 and they all sound better than my two class AB Onkyo amps (A9010 and A9150). They are clearer (which for some may mean brightness) and the speed and control of their bass reproduction is better. They have the same power as the Onkyos. I don't understand why they would sound worse, unless you like the slightly soft sound of inexpensive AB-class amplifiers. However, none of them compare to the level of my XTZ A2-300 and Audiophonics HPA-S25ONC d-class power amplifiers.

@jimc9823 Год назад

Fantastic video! Few people ever cover this. This high frequency sound you speak of could be unfiltered switching frequency noise (all class D amps use PWM - Pulse Width Modulation signals (square waves) that are then converted to sine waves using a low pass filter) this square wave at 0 output is running at 50% duty cycle and is still at full amplitude (usually running at a frequency much above our hearing, at least above 40Khz ). Problem is... some times the filters don't do a great job (bad quality or not a steep enough slope) and some of it and/or harmonics of that switching frequency waveform get through. I don't use them anywhere near pets.. My dogs will split the moment one is turned on in a room. A properly designed amp will not have much of it sneak by, and if it does won't be noticeable.

Hi Andrew, timely video! I have no way of measuring frequently response as you do. I actually purchased the Ayuma A08 about a month ago just for fun. Just to see what it would sound like connected to my existing system. I had it drive my Paradigm Signature S8 towers. I know that's a little ridiculous but I am truly amazed at how well it drove them. I only listened through blue tooth and Spotify off my phone, so really not the ideal for quality and yet I have to say I was surprised at the sound quality and even more so at the levels of volume it reached. Not replacing my Anthem separates with it😁 but it definitely surpassed my expectations. Great video as always!

When settling into a good listening session it is paired with the SMSL-SU9 through the Schiit Lokius. My speakers are Sony SSCS5 paired with an Acoustic Audio PSW8 sub. I typically listen at ~70-80db, but the sound is clean and clear up to and well above 100db as well. Good times! Love your videos!

I love that these cheap amps are getting as good as they are. I had some passive Klipsch speakers sitting in a room unused and wanted to put them in my garage. The V3 was perfect for the job. Does it sound as good as my Yamaha A-S1100 or Denon PMA-600? No, it's missing some of the warmth that I like from those amps. But it's close and more than enough for a second or third setup. Heck, it blows the pants off the first amp I got back in the day when I started getting into audio and I would have loved to have the V3 back then. The barrier to entry for good audio is getting lower every year, and that's fantastic!

@basberends332 Год назад

The Fosi Pro you recommend is really awesome. It costed me less then 100€ incl. tax and it replaces a full A/B power amp of honderds of dollars/euro’s. No lack of bass at all. The Bluetooth is really good. A good DAC with pre amp and volume Control is 100€, spdif out from your smart tv and there you go!

@don1946 Год назад

Good job and great advice. I recently set up a small system in our study with a pair of reference KEF 70s speakers and a Polk psw 10 sub. I added a Aiyima Ao7, Do5, and a Fosi tb10d just to see how they sound. One thing you didn't discuss is volume controls are way to sensitive on most of these amps. generally, the sound quality is pretty good with the Fosi a little fuller and the Ao7 a little thinner as you described. The Do5 is a different case as it has so many tone profiles and adjustments but when set flat it is a bit harsh. With each amp and placing my ear right next to the speaker I didn't hear the high pitch sound you described? Anyway, these can be fun little amps to experiment with if you in fact expect them to impart their own sound signatures and don't expect giant killers.

@walterhirt2643 Год назад

I purchased a FOSI Audio BT20A to power a pair of Polk Atrium 6 outdoor speakers. I did this because the outdoor speakers were previously being powered by my Onkyo TXSR-805's Zone 2 input that did not have Bluetooth connectivity. After plugging in the speaker wires to the new little amp and my Onkyo Pre Out, I must say, I was impressed. I feel the sound was equal to, if not better, and I now had Bluetooth connectivity. As noted in this video, I think there are some great use cases for these little amps, but I would definitely look up market to power full size speakers or a home theater, especially if you have a more discerning ear.

@luffy8049 Год назад

I got myself the Aiyima A07 and paired it with Kef Q350 speakers. I have no issue with the amp. I also have no distortion at all (even at full Volume). Maybe because the 230V in Europe (Germany) is cleaner(?). I changed the OP Amps with Sparkos Labs ss3602. After this upgrade the Amp sounds even better than the NAD C316Bee V2 (400€ class A/B) on my Kefs Q350. Power output is also great and also no weird sounds or hisses at over 80 dB. Before I bought the Aiyima A07 I had the Arlylic A50, but I was kinda disappointed. Max Volume was like 30% on my Aiyima and the sound was very flat and harsh. The Aiyima has no features aside the RCA and Aux inputs, but this is all I need at the moment and for half the price it serves a better job for me and sounds better then the Arylic. Maybe my Produkt is on of the better ones and you got a bad one.

@RUMBLEGO1 Год назад

That was i was wondering too is if they probably received slightly defective amplifiers? I own two Aiyima A07's and they sound really good! Not hearing what they are hearing with that high frequency anomaly. I think many people know that the advertised specs on these amps aren't as advertised. But i've seen tested many times that the A07 comes in a solid 50w at 8 and around 75w at 4ohms. Plenty for all of my different speakers. Surprised they were having difficulty driving those very sensitive Klipsch's. That's what is leading me to believe there may have been something defective with that amplifier. That should have been crazy loud.

@luffy8049 Год назад

@@RUMBLEGO1 As much as I like Andrews Speaker and Amplifier reviews, this one I don't. He either got a defective unit or just the power supply has some unexpected interference that causes the hissing noises or it's a biased review against cheap but good audio Produkts from "no-name" Brands. I like how he is going through all the specification of the Amp, but it's kinda pointless to match a 80-100€ amp with a pair of Speakers that costs 1500€. I understand that it's just to test what the aiyima is capable of but in the real world no one would do this. When listing with the Aiyima on my Kef speakers I knew there is more headroom and It could sound a bit smoother and more open, so I decided to upgrade the op amps. This upgrade lifts the price of the Aiyima to around 240€ and for this price you can also get beginner class A/B Amps like the Cambridge Audio AXA25. But the sound of the Aiyima now is more rich, detailed, open, smoother and cleaner. You are just left with the two inputs, but have sound in the 500-800€ Amp Price range. At least in my subjective experience.

I also have KEF Q350s with Aiyima A07 and agree that it's very good for the price. I don't hear any noises from the Aiyima at all. It's very clear, dynamic, airy and open, with a high startle factor and presence. It beats out the softish, less pure, underpowered Cambridge AXA35 when I compared them. Where I do agree with Andrew though, is my Aiyima class D and SMSL class D amps lack weight and a rich midrange, so always sound leaner than Class AB amps. And once you live with them for awhile, you'll notice the more detailed Class D sound, is less involving than a good class AB amp.

@peterwalkerden6778 Год назад

As someone who owns the Aiyima. For me I purchased it as a replacement for a used Cambridge amp that had noise problems. At the price that the Aiyima was, it has enabled me to listen to music on my cheap Wharfedale 9.1 pair in my small London apartment. Although I do agree with the criticisms in the video, I think you have missed the point for why these get bought. Typically they are a stop gap purchase for those not wanting to buy used gear and also do t yet have the funds to buy anything better new. Everything in my system was purchased new and I was aware of the limitations they came with. But I would rather be listening to music for a year than not, whilst I save for some upgrades. Plus I did have an issue with an Aiyima product and they sent me a replacement unit no questions asked without the need for returning the original. Which is probably better customer service than many known/traditional brands. All in I am happy with knowing I spent very little and have listened to lots of music. Not ideal but as we all know non of us will ever really be happy with any setup. As we look for the elusive perfect system.

QOTD: I had purchased a class D SMSL DAC/amp combo for my home desk. I returned it the next day and got the Schitt Modi DAC instead. I used a big Realistic amp from the 80’s as an amp. I just recently got the G-horn from Schitt and paired it with the Modi. Sounds great. 15 watts AB and I’m a happy camper. Yes, it was $300 but space on my desk is a premium. Nearfield listening only but can rock the guest bedroom/office okay with 90 dB bookshelf speakers. Venturi V52s. Good take on this stuff. I think the application here is absolutely critical. 🤘🏼🎸🤘🏼

Dear Andrew and Wendy, Thoroughly enjoy your videos and admire the fact that both you and Wendy can enjoy music and communicate together with it! After all , it's all about music, not effects or bells and whistle~ Thank you for bringing this review out on these cheap little Class D amps. I confess that I am a happy camper of this little Aiyima A08pro. When I was first presented this little Aiyima A08pro to try out by Doctor John, I was a bit skeptical indeed. Using the stock power supply with 32V, it surprised me since it does have ample power to drive my Dynaudio speaker with the notoriously hard to drive first generation Esotar tweeter to a respectable level but may sounding a but hard when played loud and lacking the u;timate musicality in my 200 sq.ft living room. One thing that chages it completely, I inserted an Elekit TU875 tube preamp to pair and only when this time synergy happens. The overall musical presentation, dynamics has striked a perfect balance and bested my highly regarded AVC preamp plus 47Lab Gaincard (duo Power Humpty) combo . I did not expect results like this at all! Aiyima was regarded a little toy to me and I was well expected to say a few good things or not even and return it to manufactuerer but this little gem ended up fixated firmly into my setup at the end! Right now, I can fully immerse into music compeltely and be able to understand more on how the musicians interpret the music pieces and pick up all the nuances of every small bit of essential music details with tons of harmonics and overtones! This little Aiyima A08pro may not suit everyone but in my setup, it excels and surpasses performances of my previous setups and makes a perfect match to my Dynaudio and have me uncover further potential of the speakers. Despite it sounds too good to be true, but I am comparing my combo to a lot setups times and times more expensive from my friends and I don't feel a bit inferior and in fact, I'm preferring my setup in terms of added sheer musicality and music immersion which is what I treasure most! For all those who bought these little Class D amps, before you cast this amp in stone, be sure to pair it with a decent tube preamp to ameliorate the harshness and edges , perhaps you can get similar or better sound like the Heaven 11 Billy integrated amp (at fraction of the price to the already bargain price of Billy) which hsa housed a tube line stage and class D amplification within the unit~ Andrew, before you packed it back in the boxes, please give them a try with a tube linestage or even a tube buffer and see if you like it! cheers and keep up with your great works!

My office setup consists of a Marantz slim series receiver that would go into protection trying to drive my Wharfedale speakers that dip before 4 ohms. I added the Fosi TB10D as a power amp through the Marantz’s pre outs and not only does it sound better, but the amp runs cool and has never shut down. And I have tone controls that really work! We can disagree, and that’s ok.

Ok, I agree to a point. My grandson's girlfriend listens to music on her iPhone. These amps would be a huge upgrade with a cheap pair of speakers for someone just getting started in audio. And we need young people to start trying component audio. I have several hi end systems myself however, I also have two of the Fossi Audio TB 10D amps. One is in my mother's garage with my pool table and another one is in my garage with my wood shop. I stream from my Iphone connected to a Audioquest red Dac and connected to inexpensive bookshelf speakers. They both sound great for the purpose. They also only cost $60.00 each on sale. I would highly recommend these amps to someone getting started and for someone else looking for audio in a shop or garage. I have no problem with the volumn in a two car garage. The Fossi audio with the tone controls is very useful for controling the hi frequencies and perhaps the bass.

I recently moved in with my son (he’s a gem) and his system has my old Yamaha TSR 5800, I.e. “Costco special” 5.1 receiver. Rated to 6 ohms. I replaced his mid-fi Polk bookshelves with Emotiva T2 towers rated 4 ohms. Now, they were driven for sure, easily 88 SPL, no shutdowns. But they sounded a bit dull. No treble sparkle, little articulation in the leading edge of bass notes. So, not expecting much, I hooked up my SMSL DA-9 Infineon Class D amp. Easily, immediately better at all volume levels. Paul McCartney’s bass gets truly low in “Come Together.” The SMSL handled it nicely. Happiness for 2 channel but what about surround? Well the Emotiva have two sets of jacks for bi-wiring. I just “added” cabling to the unused jacks for a “dealer’s choice” of amping. I assume that if both receiver and SMSL amp attempt to drive the speakers simultaneously then truly bad things will happen. So when done with 2 channel listening I don’t just turn the SMSL off, I also unplug it. (Hooray for 3 pin detachable power cables!). There’s a lot to love about the entry-level Yamaha “sound shaping” features, but they can’t make up for a so-so amp sub-system when wanting 2 channel IMHO.

These are desktop amps. If you need something that takes up little space and can drive real speakers with ease, than that's what these are designed for. Many have great inputs/outputs (subwoofer support, etc.) and they run cool and the signals have been clean to my ear, as in no high pitched whine---at all. Maybe you need to check on your power delivery (A/C outlets etc.), it might not be as clean as you think it is. Just a suggestion.

@D1N02 Год назад

I have a Fosi TB10D. I think it is a nifty little amp. I haven't experienced any kind of noise from it even when turning it up all the way and listening carefully near my speaker. I do hear a clear and annoying buzz coming out of the power supply itself when no sound is playing.That is not transferred to the speakers. I think it has a use case but not necessarily for an audiophile listening experience in my living room. It is very portable and takes up almost no space. I agree you should use speakers that are a bit rolled off. It can drive my 87DB Quadral Maxi 440 Outdoor speakers fine to pretty big levels. A good party setup. Not a critical listening use case. I also use that in my bedroom where I have to turn down bass quite a bit an up the treble a bit. (Partly because they are right against the wall due to space issues). I haven't tried any of my larger speakers with them, because I wouldn't expect that to sound any better than the Class A/B vintage Sansui's I have. My intended use case for it is a light weight mobile setup (phone/tablet>dongle dac amp>light weight speakers). For that that it works great for me. I am interested in the BT20A pro because you can roll op-amps, but you can probably achieve more with a little tube pre-amp/buffer (less than 40 dollars until you start rolling tubes and replacing op-amps, which you should because the improvements are massive) in front of one. I think they are fun little pocket amps to play with. I never considered one to drive my main system. If you keep a use case in mind like I have for them I would fully recommend one. But they are not audiophile material. Although I am curious how far you can improve on them with a better power supply, op-amp rolling, tube amplification, better capacitors. I realize I would very quickly exceed the price of a AXA25 or 35 that way or a AXR-100 but it is fun to play with and that is also worth something. Do not fear a lot of people will get these amps anyway because they are very cheap and they will end up with a sub par experience. What ever you say they will get one anyway. Probably a worse one than any of these because they are more convenient because they are in a cheap sound bar you can bluetooth to.

This video is a great service to the audio community. I've been skeptical of these amps because of two things: (1) case temperature vs reliability, (2) power vs size. (1) 300W at an optimistic 95% efficiency is 15W amp dissipation. 15W will result in a high amp case temperature, short amp life or failure, likely destroying the speakers (2) A 48V power supply requires approx 14,000uF of output capacitance to deliver 300W (allowing for 10% voltage droop between 120VAC cycles). A 1000uF 50V capacitor is 0.5" dia, 1" long, where is all that capacitance in such a small amp?

Lots to unpack here. I have Aiyima, Douk, and Fosi amps, Topping E50 and Ifi DACs, Echo Link and WiiM streamers and Sony, Polk, Jamo, Mission and Tannoy speakers with Polk and Yamaha subs. So, I’m invested in good, cheap, audio, man. I’ve always taken the power ratings with the appropriate amount of salt. I've never had the issues you ran into. I also have a Yamaha and two top shelf Sony AVR’s in the big rooms and some embarrassingly huge older Onkyos in the workshop. I’ve followed a variety of high follower audio reviewers for years now and you are the first to discover the issues you report. I don’t believe for an instant that you are motivated to discredit other reviewers or protect your supply of higher dollar equipment. But if ALL of the amps exhibited high pitched whines when no one else has noticed this, some more investigation or attempt at measured explanation may be in order.

I started investigating surround sound over 10 years ago and asked a similar question about the T amps - an amplifier on a chip. The reviews had a lot of good things to say about these 10 - 20 Watt amplifiers. Working as mono blocks, bi-wired for the stand mount passive speakers I already had and not costing anything close to the multi-channel amplifiers. I never got a response and nothing on how they compared to other mono-block amplifiers. In the end I went for a five channel Meridian G55 eventually replacing it and the three pairs of passive speakers for Meridian active speakers (two pairs and a centre) and recovering over 1000 GBP in cash. I can see why HDMI eARC would be useful for an alternative to a sound bar or a pair of powered speakers but so would USB audio from a desktop or laptop.

Most times the noise you're hearing comes from the power supply brick. I would not use a 48volt 10 amp supply. That's courting disaster as it's too close to upper limit of the components used. Most diy forums reccomend 36v 10amp for the amps that use the tpa3255 to chip like the Aiyima A07 or similar. That gives you the same available power as a 48volt 8.3amp supply. I use a cage type power supply at the 36v 10amp rating and get no noise. Cost is about $40 including cables. Also some of the units have swappable opamps that can improve the sound. That's an additional $12 to $20. I went for the opa627 modules which ran $20 for both channels. Lastly these amps are meant for budget systems. I don't know of anyone who would expect to use these in a system with the speakers you used. The best I have used are the Elac Debut 2.0 B6.2s.

Living in Australia most US based prices are effectively doubled when taking into account currency conversion and import freight costs. Late last year I was at the point of choosing between a cheap(ish) dac amp config or putting my money behind an integrated amp and speakers. Watching various content creators including your channel and reading other reviews on a wide range of products, I decided to go for the Yamaha AS301 amp coupled with a pair of Dali Spektor2 speakers and I haven't looked back since. I love the richness of the sound coming out from my turntable, and whilst some reviewers have said to consider an add-on subwoofer to the mix to augment the Dali's, I have found that the Spektor2's actually give a decent level of low frequency and whilst not hitting the bottom end fully, they still produce a nice deepish bass sound.

I'll throw in my experience. I first set up a "proper" home theater 12 some odd years ago with some Polk TSI100s as my primary. They were, you know, fine. Finally decided to go further into the hobby a couple years back but kept the old Polks in my closet since their re-sale was essentially nil. In the last 2 months I turned an old closet into an ultra-mini home office (think 5'x6'). I knew I'd be primary listening to anything in there with headphones, but hey, I had those Polks, why not set em up? After plenty of researching and debating, I just got over myself and got a tiny Fosi 2 channel amp with bluetooth. It rocks. It is more than I could have asked for. I find myself just chilling in there with some soft music all the time. I have a whole living room with an expensive, calibrated system... but honestly the vibe in my little Hobbit hole makes for a better overall listening experience.

@jake46467 Год назад

As someone who owns and uses two Fosi TB 10 D amps I’d say these inexpensive pieces are the epitome of ‘right tool for the right job.’ For me, each amp powers a set of Atmos speakers through the pre-amp on my A/V receiver and they’re great in my room. Do they compete with the Crown XLI amps that power the other speakers? Of course not. But they do the job and they fit what was left of the budget; I’d rather have somewhat compromised Atmos than no Atmos. I also liked them for reasonable volume 2-channel listening…a bit one dimensional but really fun and engaging. I can see the downsides and expectations definitely need to be managed. But to borrow a phrase from the photography world, the best amp is the one you have. That $5000 amp on the shelf over there that all the audiophiles rave about? It’s probably great. I’m also never going to buy it because that just isn’t the audio sandbox I play in. But I’ll be using and enjoying the Fosi(s) tonight and that has a lot of value to me personally.

@@KristiWright If I witness something spontaneously awesome and all I’ve got is my old cell phone camera should I not take the picture? Using these amps for anything professional or even mid-tier is definitely using the wrong tool for the job. They’re not ‘giant killers’ in any way. But I don’t think that is what most people are doing with them. They’re in garage systems, or desktops, or attached to a kid’s first set of passive speakers. Or providing supplementary Atmos where there was none. I think they’re great for those types of applications.

@Jake respectfully, Kristi is NOT saying don't take the picture. I think we're starting to mix a few too many metaphors when we can just keep it to audio. As stated in this video, for nearfield, casual or ambient music level listening these amps MAY be enough or MAY work fine and not damage one's speakers. But for those who claim these amps are "the best" or "best amp I've ever heard", I hope this video urges some caution, because the term "best" --even if at a specific budget --should be reserved for applications where quality, accuracy and reliability DO MATTER. To that end, these amps do not appear to hold up. That's all I'm saying. If you want to throw one of these in a garage and rock out while doing woodworking projects or wrenching on a project car, I say, DO IT. Do it because if you get sawdust on it or a little engine oil you're not likely to care too much --same story if listening at 30-40dB at your desk so as not to piss off your office mates. Hope this helps clear things up.

My system is made up of this little amp combined with a Schiit Modi+ and a Sony DVD player as a CD drive and a pair of JBL 530s. I am so blown away by the total sound that I find it difficult to pull myself away to listen to any one of the five other systems I own any of which cost easily more than 10X the price of this new little system. BTW, my Aiyima came with a 32v 5a power supply and it will push the 86db sensitive JBLs to ear splitting levels. I can not discount your experience but I think it is important to share another side. I generally agree with Kristi's and your opinions in your reviews but in this case I must disagree with your assessment on the Aiyima. On a personal note for Kristi, I wish you would appear on Andrew's side of the camera more. I think you look great and possess an engaging personality.

@praneshsarangi Год назад

I own a Aiyima A07 which I use to drive a pair of Wharfedale Evo 4.1 speakers in my bedroom. I use a 36V 6A power supply sold by Aiyima which has no brand on the label. I have also used my MSI Laptop's Chicony brand Power Supply - 19.5V 6.15A. Both the power supplies can drive the speakers much louder than I can tolerate. I often use my Shanling Q1 digital audio player or my MSI Laptop to play music mostly from FLAC files. I am very happy with the sound A07 + Evo 4.1s produce. It took me a while to set up the speakers correctly with some toe in. Now I enjoy the music with good stereo separation and imaging. It doesn't look like the sound is coming either out of the left or right speakers. The speakers disappear. I can identify where the instruments or vocalists are located. I can even feel the size of the environment like a club or a large auditorium or an arena. The sound quality is great. With the 36v 6A power supply, if I keep the A07 on and the RCA cable (Cable Creations) unconnected to any source like my Q1 or laptop for a long time then I could occasionally hear a faint hum. As soon as I connect the cable to a source the hum disappears. I replaced the RCA cables (Amazon Basics) and the hum disappeared. If either of the RCA cables are connected to a source and turned on but no music playing then there is no hum even if the A07 is kept on for hours together. I have turned the volume knob to maximum and with my ears next to the speakers, I have not heard any hum or any noise. Only silence. I think the hum is caused by the quality of shielding of the RCA cables which picks up some inductance from other sources of electromagnetic interference. I have a fan in my room. I once tuned that on at full speed while the A07 was on and the RCA cable was not connected to any source and the hum appeared. That is what made me suspect the cable was picking up some electromagnetic intereference from the fan motor being the source of the signal causing the hum not the amplifier. So, if I have stopped playing music I continue to keep everything connected or I switch the A07 off. So, I don't experience any hum.

@praneshsarangi Год назад

The reason I typed this long comment is because Andrew (whose recommendation of the Evo 4.1 influenced my purchase), says all the amplifiers have a high frequency noise or distortion. While I am not a technical expert, my gut feel is that the amplifiers may not be the source of the high frequency noise or hum but the RCA cable may be the problem. I use a Aiyima A07 which was not a part of the list of amplifiers Andrew tested, so it is also possible that Andrew is right that the ones he has may have a problem. Mine doesn't.

In about 2010, I found on clearance a Polk LSI 5 speaker set. So, I bought it, and they threw in a sub for the price, and I brought it home. I hooked it up to my amp, and it hardly produced any sound. I started poking around, and I found out it was a 4ohm speaker. Very few amps can power a full set of 4 ohm speakers. The ones that could in home audio were over $10k. Macintosh was one of the few. So, I knew a guy that was an audio engineer, and as I had been a hobbyist in pro sound, I gave him a call. He told me that in a blind test almost no one could tell the difference between a Macintosh and a (at the time) $280 Behringer A500. The Behringer A500 was a studio reference amp. I didn't believe him, and he told me to bring my fronts down to his lab, and he'd prove it, but he wanted to take reading from them in exchange. So, I did. He was right, I couldn't tell the difference in a blind test. Neither could he or several other engineers in the project. The computer could barely tell a difference between the amps. Those LSI speakers sound really good driven by 3 behringer A500 amps with a Yamaha RXA AVR. If I was to do it again, the only change I'd make is to drive the fronts with a bigger A800. The A500 is still reasonably inexpensive, and the design hasn't changed since I bought mine. If one were to blow, I could go to any Behringer seller and get a replacement on any weekday.

Andrew, glad to see you taking a look at these cheap class D amps. Your opinion is always a helpful guide. I own the Aiyima A07, measuring a true 50wpc@8ohm and 90wpc@4ohm at 1%distortion. Regarding your noise problem, both my Aiyima A07 and SMSL TDA7498E are quiet as a mouse. But neither have tone controls, and perhaps that's the source of your noise problem? I use KEF Q350s with my Aiyima A07 and it's a very good amp for the price, easily beating out the puffy, less pure, and weak-as-a-kitten Cambridge AXA35 which was a big disappointment after reading rave reviews, so I returned it. The Aiyima A07 is very clear, dynamic, airy and open, with a high startle factor and presence. It's not a giant killer of course, but it's surprisingly good for the price. However, I certainly agree with you regarding the tone of cheap class D amps. As clear as they are in portraying budget class AB amps as fuzzy and less detailed in comparison, budget class D amps all lack body and weight. You'll never hear them described as rich. They always sound leaner in the upper bass, lower mids, as you point out.. And once you live with them for awhile, you may grow to realize that the very detailed Class D sound, is more clinical, and less involving than a good class AB amp. At least that's my experience. Before you throw the baby out with the bathwater, it would be interesting to hear your take on the noiseless Aiyima A07, the best of the cheapie class Ds.

@lisar3944 4 месяца назад

I had the same experience with the ao7 - it's a remarkably sweet little unit, and it's disappointing that the the components discussed here are among the worst of of the worst in this class of gear. I gave my a07 away when I got an smsl da9 which is much weightier in bass regions (though slightly less detailed) and it's really a fun listen, but you're right - at least ime - that class D still needs some refinement to really sound both detailed AND full. I personally am planning to order the Fosi ZA3 when it's available again, as I think being able to easily roll the opamps could be a game changer - there are already some youtube videos that sample the unit with different opamps installed and the differences between them are surprising!

@geevee1045 4 месяца назад

I own the Fosi ZA3 with 48v supply and it is an improvement over my Aiyima A07. It also has a proper subwoofer output. And when 2 are used as Paralleled Mono amps, it doubles the Current output to drive difficult low impedance speakers. This means a 3 or 4 ohm speaker will look like an easier 6 or 8 ohm load. But I suspect the extra cost of expensive opamps will propel this cheap amp into Rotel A11 category and I'm not sure if it can compete at that level. I haven't heard the Rotel A11 but it also includes tone controls, 2 pairs of speaker outputs, Phono and BT. @@lisar3944

Gotta disagree on this one. My a08 amp works fine outside of the "near field" for me. I don't know what preamp you were using with the a08 or if you were using a preamp at all. The a08 is HIGHLY dependent on a pre amp like aiyima T8, that's why there's a cut out for it to sit on the amp. With the T8 and aO8 both at 70% volume, it pushes my Sony SSCS5s beyond my comfortable listening level. You should have reviewed them as a pair. There's also the question of equalization. Recommending that people not buy a cheap amp simply because it requires good 10 band equalization from the source is silly IMO. Yes these amps require additional purchases to make them good but that doesn't make them a "bad value."

Furthermore, there was inconsistent balance between the channels and worst of all, the PA5 failed within a month.
