Aiyima A07 Max With Sound Comparison 

Love your reviews. Keep up the great work. Looking forward to the monoblock review.

I have 2 of these coming mid-January. I'm using them to drive my main speakers which happen to be on my desk atm. It's a Delcoid satellite/ subwoofer setup from around 1980. I'm concerned about them driving the sub as it's a 12" passive that can handle 500 watts rms. If these amps can't push it, I'll be returning them the same day I get them. I'm using a QSC GX5 amp right now. It works great with 500wpc but it takes up too much space on my desk. I'm disabled now and live with family so space is at a premium. Great review and you earned a new sub ! Thx for the info ! UPDATE: I've been running these amps for about 6 weeks now. I'm happy to say that they sound very good with my system. My 12" passive sub still hits hard but it's also controlled. No sloppiness here. I'm still amazed. I never thought that a class D amp could perform this good. I can't see how ANYONE would disappointed with these amps. Of course, don't expect them to outperform an amp that costs several thousand dollars. They still aren't as good as my GAS Ampzilla but unless I'm sitting back being VERY critical, I can't tell the difference. For every day listening for most people, the A07 Max will do the job nicely.

I love your channel. Thank you for informing and entertaining without droning on or insulting our intelligence or talking too technically. As dumb as I am I can follow along well. Tim in Texas

Fun informative video mate, thanks!

I love the way you do the reviews . 👍👍👍

Another great video, can't wait to see the next one

Nice video, thanks for the upload

Both make sound, that's it. The looks inside I like very much.

Great review! Aiyima is more balanced, less v-shaped, and therefore.....better :)

My fosi audio v3 just arrived and I am listening to it while watching this video. Hope I don’t regret 🙈

LIKE number 1 which is always fun and all the waaaaaaaaaaaaaaaaaay from Canada. :)

I could replace some part in aiyima because it has neat design. And better form factor, to stack with bluetooth receiver, fiio br13

Aiyima sounds more open. It has more transparent sound.

Listened to the sound tests on my home theatre system and with my AirPods and the only thing I could pick up is maybe the Fosi has slightly more bass coming through? Other than that, they sound identical to my ears. Will you be getting in some of the mini amps with the optical and usb inputs and the subwoofer pre out? I see both Fosi and Aiyima have them.

Took a bit to get used to your presentation, I'm all good now! I just ordered a pair of these A07 Max units, Amazon is selling them for $74 a pop here in the states. I already have the Fosi V3 and am being blown away by the sound coming out of this stupid little amp. I discovered that by boosting the line level input voltage that the sound improved greatly. I used a Douk Audio line level booster, $45 on Amazon. I also have the Sparko op amps, they muddied up the V3 so hoping the A07 will be better and play well with the Sparkos. We will have a three way shootout with a Sparko loaded A07, a stock A07 and the Fosi V3. Going to be fun!

The differences between these two are minimal sonically, aesthetically I prefer the A07 max myself.

Have you considered testing SMSL SA400, it beats many so called esoteric brand at less than quarter of price.

Hello. How does the sound of these amps compare to the sound of the Rotel integrated you have there?

I love these amps and there great for budget applications. However save a bit more and go for the Sabaj A30a 100wpc into 8ohms onboard dac and a bass low pass filter (no high) .. It sounds head and shoulders above these units, if you shop canny, you can pick one up for £425 . Its insanely good after 50 70hrs burn in . 90% out of the box . Great and refreshing review..

Before you "experiment" with mono aiyimas...can you swear you can hear cross talk while listening to one of them in stereo?

A quick way to know how much real power might be available with these class D amps is... Wattage = Amperage times Voltage. So, with this power supply. 36 volts times 6 amps equals 216 TOTAL WATTS POWER CONSUMPTION THAT IS EVEN AVAILABLE. In addition, most class D amps run around 85% efficient to their output. So multiply that total power consumption of 216 watts by 85% efficiency (.85) and that equals around 183 watts total. Divide that power by 2 as there are two channels and that is about 91 watts per channel maximum that can actually be made with this amp. Internal caps "might" improve the short-term power bursts slightly depending on the impedance of the speakers, but the power output specs are usually complete marketing vaporware. These amps are not bad for the money, but everyone should know these huge marketing power specs are not real when looking at these Class D amps. Even if purchasing the 48-volt power supply, it is only a little over 100wpc. I would not suggest using a 48v10amp power supply for these as one might have a meltdown eventually.

Aiyima sounds lighter and more transparent!

How about the volume dial on these two to push power both are at same level?

All these lower cost amps, as good as they are, have one fatal flaw IMHO... their volume knob acts as the power switch. They need a dedicated power switch so you can leave the volume set to your desired level. That would make them perfect for use as an extra amp for AVR systems that need two more channels amplified. Many are 11 channel capable, but only amplify 9, leaving you to provide an external amp for the last two (typically your AVR's rear height channels, like the Onkyo TX-RZ50). I plan to buy one and manually add a power switch. BTW... peak/max power means nothing to me and is a miss-leading spec, these manufacturers need to supply true RMS power (continuous) which is way less than peak.

Fosi a little bit more dynamic, but also a little bit grainier?

The difference is so insignificant that I can't even hear in whose favor.

This time I cannot tell if Fosi sound more like Aiyima or Aiyima sounds more like Fosi...

fosi has a bit more bass punch

If I only knew if my A07 Pro is in the same league than the ones you have tested here...

You use in Fosi 5532 Op amps?

😊😊😊

YIMA SOUNDS FLATTER MORE NATURAL

Is it me.....or the sound it's exactly the same!!!!

Sorry but your Rotel gear deserves better spkrs than those polks

A07=V3 same sound quality

fosi has much more dynamic in all frequency ranges, in the bass the fosi is more stable, the resonances in the bass are out of control with the aiyima. the mids are much more detailed with the fosi, the highs slightly more pronounced. the channel separation is better at the fosi which gives you more room and depth. the aiyima is more flat less dynamic overall. however, the frequency response seems to be pretty much the same and this is why people without good listening experience cannot hear the differences. there is no difference in 'color'. but now the important shit: inthe fosi v3 you will find the cheapest opamp on the market, the ne5534. and multiple persons did tests either with better opamps like the ad797 etc. or with very nice discrete opamp replacements like from burson audio etc. and these options give you even more dynamic and good control in the overall feedback loop of the amp. also again a tiny bit more channel separation. however, if you want to have the ultimate channel separation, you upgrade to a dual mono setup and it is worth it. thanks for the test. it helped me in making my decision what to buy.

Too much clowning around.

Acting like a clown seriously damages your credibility...plus it's just annoying...😖
