I appreciate the effort you put in creating Fiio K9 pro ESS video. It came out very nice. Top channel!

@PassionforSound 2 года назад

Thank you Kris!

@moculus2063 7 месяцев назад

Wonderful review. Much appreciated. What reviewers rarely mention is ease of compatibility with powered speakers. The K9 is a full desktop solution and full includes speakers. I just received mine and its connected to iLoud Micro Monitors. The one complaint I have is the sound initiation lag through USB. Its a second or two at most, but every time a source changes (even between videos on RU-vid) there is an initial silence before the audio kicks in. No delays in video, just sound. Never experienced that before with other devices.

@PassionforSound 7 месяцев назад

That's really interesting. I didn't have it hooked up like that because I was focussed on its audio performance. I wonder if there are any settings available via the app that could be causing that.

@nippohippo3257 2 года назад

Awesome review as always. Great to see it compared to mojo 2 and dx5. Thanks a lot for the review man. I have seen you review Burson products, any chance we get a Playmate 2 review? I would love to see it compared to K9 Pro ESS and also with the similarly priced Hifiman EF400.

@Rakshit0076 2 года назад

The Fiio K9 pro definitely creates a Fomo for someone like me who uses the Topping dx7 pro that's powered by a single ESS 9038 pro dac chip. Yet to find a comparison between the two. I think I'll stay put with the DX7 pro for now, but i am not sure for how long 😁 Great detailed video as always.

@PassionforSound 2 года назад

Glad you liked the video and sorry I can't give you a direct comparison. I actually doubt the K9 is vastly better despite the dual chip design

I'm actually working on that right now 🙂 (as in getting some to review)

@dan110024 Год назад

Walked out of a shop with a K9 Pro today with the intention of picking up a Burson C3P. I never got to listen to the Burson as the guys seemed pretty disinterested in it and we meant towards other units, and I’m absolutely stoked I walked away with the K9 Pro. Buying something I haven’t researched to the nth degree was kind of invigorating and freeing. Like the old days. Great review! You’re an absolute master at articulation.

@PassionforSound Год назад

The K9 Pro is an excellent device, Dan. You've done well 🙂🙂 (Glad you like the reviews!)

@dan110024 Год назад

@@PassionforSound just wondering what your take is on some amps (and headphones) being more prone to cause tinnitus than others? I swear I dont have it turned up to unsafe levels but I seem to have more tinnitus than I ever have in the past week with the K9. I use them at work for a number of hours each day. I’m powering my Aeon Noire’s with them and listen to mostly music scores, a bit of other classical, and some pop. I had read a comment someone made about another amp causing them to have tinnitus but just thought they were imagining it - now I’m wondering if it’s a thing. Either that or I did have it turned up too much for too long. It’s my first set of cans, so maybe it’s something I’m not used to? Anyway would love to hear input from someone who’s listened to a few amps and headphones in their time!

@dan110024 Год назад

Just did some reading. Im thinking it’s likely that the low distortion of the gear allows you to listen to it at higher volumes without realising. Also the brightness of the Noire’s probably doesn’t help

@PassionforSound Год назад

I can definitely help as someone who suffers from tinnitus sometimes and who's discussed this with a friend and patron who has the same troubles. It's more likely the headphones than the amp causing this problem I think (I'm trained in human hearing, but not a practicing professional). Are the headphones also new or have you used them before on other systems without issue? Depending on the answer to the question above, my experiences are that certain treble peaks can aggravate the ear and trigger tinnitus - this will depend on your specific sensitivity to different frequencies so it's difficult to predict and requires some trial and error. This is likely most affected by the headphones rather than the amp. Where the amp could come into play is in the character of the sound it delivers. If it's triggering your ears' natural protection system (the stapedius reflex) due to any perceived harshness and fatigue then that could potentially play a part too. Unfortunately, tinnitus isn't particularly well understood and has many possible causes. Let me know if the headphones are new or just the amp and we can maybe chat a little further (not that I can provide medical advice).

@PassionforSound Год назад

That's possible (on both counts). Maybe try the thicker inner filters on the Noires and see if that helps. Beyond that, just be careful with your hearing and see if quieter listening can also improve things.

@kirbykrause7866 9 месяцев назад

@guystpierrecomposer 2 года назад

Hi Lachlan, very good review as always! Did your hear this ECM album by any chance? HAFLA by JON BALKE, SIWAN. It is so good and well recorded, amazing micro dynamic and tone! Great for testing dac in my opinion. If all album sounded like that, the eq on the mojo 2 wood be totally useless :) P.s. Your mic sound less good than usual. It seems that it is getting more room reflection especially in the Lo mid. Maybe to much omni directional...

@PassionforSound 2 года назад

Thanks for the music tip - I haven't heard that one. As for the mic I was testing a different mic and actually messed up the setup. I appreciate the feedback and apologise for the drop in sound quality on this one

@MoozekNoizee 2 года назад

Maybe you might prefer to use a shotgun microphone at that distance, your voice sounds a bit too muffled in this video.

@EmamW 2 года назад

Have the fh3 iem and its a very good iem and its a keeper. Had the fiio k9 pro ess, plenty of depth and resolution but it never had a full note quality. Returned it and got a shanling h5. Depth, layering and resolution not as good as k9 but has a full note quality and shanling sound.

@mmorales508 Год назад

Hi there! You think this would be an upgrade from a SMSL SU9, SH9 stack? I I've used this stack for over a year with no issues for everything from music, movie watching and lots of gaming but in getting bored of the sterile sound of the SH9 and was wondering if this could be a better device for my use case. My headphones are HD660s, Drop HD8XX, HiFiman Sundara and AKG K712 Pro. Thank you for your comprehensive reviews as always!

@PassionforSound Год назад

I would stick with the stack I think. The amp in the K9 Pro holds it back a little and I'm not sure that the DAC will be that much better than the SU-9. I haven't tried the side-by-side for direct comparison, but I'm fairly sure that will be accurate

@mmorales508 Год назад

@@PassionforSound I think that’s a good idea. The SU9 is a fantastic DAC for the money if anything I’ll upgrade the amp later on. Thank you for your advice! Looking forward to your next video 👌🏼

@kristaps2010 2 года назад

Strangest abnormality I found with my fiio k9 pro ess is sound problem on TV each HD channel. There is no normal sound, it’s only noise kind of flickering. Normal channels run fine. I connected my TV via optical. Turned fiio off/onn, problem still persists. Any similar experience?

@PassionforSound 2 года назад

I haven't used it with a TV. Do you have a different TV you could try to check if it's the TV itself causing the issue?

@disco4535 2 года назад

Other reviewers have said that the equalizer in the companion app only affects the bluetooth outpout and not any other outputs. Maybe it's different on the ESS version?

@PassionforSound 2 года назад

As a non-EQ user, I actually didn't check that. It could well be correct and I'm not currently in a position to test because I've rearranged things for some upcoming reviews and the K9 is off the desk at the moment.

@rjmoyer2 Год назад

Do you recommend the K9 Pro ESS over the RME ADI-2? In the US, the ADI-2 is $500 more than the K9 right now, is the extra money worth it in your opinion?

@PassionforSound Год назад

Unless you need the specific features of the ADI-2, I'm not sure I'd spend the extra. That said, I've never compared them side-by-side...

@DaveSHarris 2 года назад

Is the Chord TT2 and Mscaler still your favourite DAC combo overall?

@PassionforSound 2 года назад

So far, yes. I'm always on the lookout for something even better and I'm excited to try the Aqua Formula DAC soon and see how that performs, but for now the TT2/M-Scaler is top dog for me

@waldowsxxghostxx8577 Год назад

What is that usb on the side of the amp for can you connect your phone via usb and play music off your tidal etc.

@PassionforSound Год назад

Absolutely! I forgot to mention it in the review - sorry. It's an extra USB connection for mobile devices as you said.

@CraciunAlexandruGh 2 года назад

Great review. I still would have liked even just a short mention on differenced between digital inputs. As for the product, I am disappointed at the limitation of the digital inputs, the DAC implementation, the SE output (only just a bit). For the 850$ requested price, I think it's not worth it unless you are severely space limited and cannot go with a dac+amp stack. The 200$ Soncoz GD1 and any ~400$ THX AMP would probably be better.

@PassionforSound 2 года назад

Sorry I couldn't cover the input quality as well - just so much to cover in this one. As for the quality vs a stack, it's rare that a similar priced stack won't outperform an all-in-one because each device in a stack has it's own power supply, etc. but then you'll also need interconnects and two power cables so it can get messy. I like stacks more in most cases, but there's no denying the convenience of an all-in-one like the K9 Pro.

@sameh9310 2 месяца назад

Ordered this unit at first for ~800€ and then saw the newer released K9 AKM for about ~500€. It has nearly the same internals except the dual AKM DAC chips instead of the ESS's (correct me if i'm wrong, the only thing i saw is that it has 2.0W max output instead of 2.1W). I Immediately canceled the K9 Pro ESS and then ordered the K9 AKM instead. It just feels like a steal for it's price with it's versatility and good DAC, i can also always upgrade the AMP part later :D

@PassionforSound 2 месяца назад

I think that's the Pro vs regular K9 you're taking about and they are both meant to be very good (I haven't tried the regular one). Hope you love it!

@Ivanleslie Год назад

Hi, between this k9 and the Sennheiser HDV 820 which one do you prefer? (I have the HD 820)

@dudexyt 2 года назад

Sounds like this is better than a Topping D90SE/A90 combo but still has the limited soundstage. Topping has a new combo DAC/Amp with the LA90. Do you have that in your review queue?

@PassionforSound 2 года назад

I would probably choose the K9 over a Topping 90 stack, but I haven't compared them side-by-side. As for the LA90, I don't use passive speakers so I don't think I'll be reviewing that one.

@MenniePlay 2 года назад

It's a lot far from Topping D90SE/A90.

@PassionforSound 2 года назад

Have you compared them side-by-side? I would expect the 90 stack to be a bit better, but prefer the form factor of the K9

What would be more suitable for HD650, Fiio K9 Pro or the ifi ZEN Set Signature V2?

@Rubiks_LIVE 2 года назад

I was wondering what your thoughts were on the amp portion of this unit and how it compares to the Asgard 3.

@PassionforSound 2 года назад

The amp stage is very nice for an all-in-one and a THX design. I'd personally prefer the Asgard 3 because it allows for depth in the soundstage, but it's also a bit richer and warmer sounding so those seeking maximum clarity will probably prefer the FiiO

@Rubiks_LIVE 2 года назад

@@PassionforSound perfect. Looks like I'm keeping my Asgard! Thanks!

@dan110024 Год назад

I have tried playing with the lowpass filters in the app and it seems like the app has taken a real downturn in reliability since you reviewed it. I wasn't able to tell any difference in the filters and then found the app had disconnected from the unit. It stays connected for a short period of time and drops out. I think an iOS update has messed with it, but this shouldn't be an excuse. Hope they resolve it soon!

@PassionforSound 2 года назад

I don't have a contact to get JDS Labs gear unfortunately so no current plans there. There's no doubt they make great gear, but my past experience suggests that the Element 3 probably competes more with the tier down like the Topping DX5. That said, the sonic differences are small and a lot of the K9 Pro's value is in the features, balanced capability and power.

@epicmike3915 2 года назад

All neutral dacs and amps sound the same. Don't let reviewers tell you differently. I demoed a bunch of them at Axpona this year. From expensive to cheap ones. My advice go with the one with the features you need. Don't spend more money if you don't have too.

@Princeton_James 2 года назад

L50/E50 is 1 of toppings best. I'm curious, but as other person commented you aren't going to hear a night and day difference.

@PassionforSound 2 года назад

The E50 is a brilliant DAC and definitely sounds different for many other DACs. It's true that some DACs are almost indistinguishable (I've called this out in a few reviews lately when I honestly don't think I could pick them blind), but it's not always the case. The E50 is a standout to me for sound quality. That said, the L50 is a bit lacking in dynamics and would likely keep the E50/L50 stack from matching the K9 Pro I think (I haven't compared them and don't have time right now to offer that comparison). If you were happy mixing and matching styles and getting the right cables, I'd expect the E50 and Geshelli E2 to be a better setup than the K9 Pro, but at that point you're getting into some serious hassles for cabling and also missing out on some of the K9 Pro's features.

@a2raya772 Год назад

is this worth the upgrade over the Zen Dac V2 with Zen Can?

FiiO is way much better than ZxR (I suppose X7 is almost the same sound card in terms of sound quality), the difference is very noticable in all aspects both when listening headphones and active speakers. When I first listened FiiO with my T1, the diffence was day and night comparing with ZxR. As for AE-9, FiiO is still better but the difference is not day and night (at least for me).

I've been primarily using the FiiO K9 Pro ESS as a DAC for the Ferrum Skypos/Oor stack. Previously I was using the Gustard X26 Pro as the DAC for the Ferrum stack. Despite the Gustard X26 Pro being technically superior, I prefer the DAC on the FiiO K9 Pro. The reason why is the Gustard X26 Pro sounds too warm, smooth and laid back. The DAC in the K9 Pro sounds very crisp, clear and energetic. I'm still somewhat taken back by how much I love the sound signature. I never saw that coming.

@dungysphincter7974 2 года назад

For a slight difference not even worth double the price of the Topping DX5. I think the better choice would be the Topping E50 with the SABAJ A10h Desktop Headphone Amplifier if having sensitive headphones. If your headphones are more demanding, then go with the L50 headphone amp....much better bargain. Things are getting much more pricy, and getting less for your money lately. $800-$900 is not exactly a budget device. This would be budget priced if you are fairly wealthy. Most people can not afford to spend $800-$900 just to get a headphone amp combo. Ty for the review though, your appreciated.

@PassionforSound 2 года назад

The L50 headphone amp isn't such a great choice IMO so I wouldn't recommend that as one of the alternatives. It's fine, just not great. The E50 is brilliant though so starting with that is a good idea if someone is happy to mix and match the look of the devices. I think for those on a tighter budget and wanting an all-in-one though, the DX5 really is a good choice.

When gaming, you'd use this the same as for any other use. Just connect via USB (or optical/coaxial if preferred) and plug in your headphones, amp or speaker and to hear your gaming audio.

I have a HD 8XX. Would you recommend high gain or medium?

@PassionforSound Год назад

I'm not sure. It's best to base it on what works for you in terms of giving you a good usable volume range to work with. There should be no sonic change between gain levels, just determines the amount you need to turn up the volume

@dustinmihalcheon5013 Год назад

@@PassionforSound I just know Schiit audio stuff actually affects what you hear if you have a higher impedance headphone or something closer to an IEM. High gain was night and day from low regardless of volume.

That will probably depend on the specific amp in question. With the K9 Pro it isn't really a factor in my experience

I have the AKM version, so I compared it to mojo 1 and found both sounded very similar only thing I found difference was bass delivery in k9 akm was bit better but otherwise they sounded same to me. Overall it good enough for me but was bit disappointed that 6 year old mojo still go neck to neck with devices twice in price in even 2021. There were some issues in akm version with those small switches. And also the dac filter only works on Bluetooth mode.

@PassionforSound 2 года назад

Sounds like they've made some very nice upgrades from the AKM to ESS version, but don't feel bad about the Mojo being on par - the Mojos are amazing devices that perform way beyond their tiny size.

I too have the AKM version and find it quite competent at it's price point with many headphones but not all. I find that using the K9 Pro DAC can drive the Focal Stellia to satisfactory and enjoyable listening levels, but not the Focal Utopia as there is just a lack of synergy. Not unexpectedly it cannot match the musicality of my (for now reference) combo of an RME ADI-2 DAC and Felicks Audio Euforia with the Utopia or Stellia. But I am happy to report that in the last couple of days I just received the Helm Audio Bolt and the DB12 AAAMP mobile headphone amp ($179.99 USD for both) and using it with my iPhone and Apple Music and Tidal along with the Stellia & Campfire Audio Solaris 2020 (without the DB 12) and it easily sounds better to my ears than the K9 Pro. If you get a chance to audition it I would suggest you give it a try.

@PassionforSound 2 года назад

I'd definitely like to try the Helm audio gear at some point and I completely agree that the K9 Pro isn't a setup I'd recommend for high end headphone listening. Having enough power is one thing and, for an all-in-one, it sounds good, but TOTL headphones like the Utopia often need a specific sound and character in the source chain to sound their best. The K9 Pro, to me, suits warmer cans a bit better and also isn't the last word in sonic bliss (and shouldn't be expected to be at its price 🙂)

@GadZookz 2 года назад

Susvara is harder to drive than most headphones but it is not as hard to drive as many people think. If one is not intent on causing hearing damage then there is no need to drive it with a speaker amp. You can even take it mobile with something like the Ibasso DX-300 if you want to risk taking the Susvara outside. But I wouldn’t. 🙂

@xray111xxx 2 года назад

This is destined to be the product of the year. The already done AKM version sold out at $699.00 USD. Now $899.00 USD for the ESS version. I want this sure, but I am captivated by my many options that may add up to the same or less and get pretty much what I want. I have to say here out of left field comes Fiio making something special. I just didn't want to and still don't want to pay $899.00 when I have such a large playing field for me that will equate a better value for me than the K9 pro is. But boy oh boy Fiio will still sell everyone of these. A hot product.

@PassionforSound 2 года назад

As I said in my first response, you have a fair point. It's very easy to miss talking about that socket during a "tour" of the device because of its location. On top of that, I tend to focus my reviews on the usability and sound quality of the devices rather than the things that can be read on a retailer or manufacturer web page. I do try to cover of the inputs and outputs, but it's not a point of emphasis for me because it's all available elsewhere and I like to dedicate the limited time for each video on the things you can't glean from a webpage.

i think companion apps are a big deal, not only is the UI more comfortable, remote and easily upgradable, it also simplifies the hardware, fewer buttons, no screens, not only a lower cost, but maybe even improved sound ? frankly i don’t see why constructors, like RME for example, or, much worse, chord, which their clownish and expensive UI don’t just use apps instead, i doubt anyone buying a chord huge tt2 doesn’t own an app, oh and chord, i can make an app for u, for the price of your next generation Dave :) (all resemblance with a real contract is false) get some app devs working on this, we might even be able to decide on a standard that will pilot any hardware. oh and finally, hardware builders would be able to offer many more parameters, for almost no cost, because it would not involve any more hardware. i find it hard to understand why audio products still have buttons to be honest, except the volume control

@PassionforSound Год назад

I think the easiest answer to why products still have buttons are all the people like me, Martjin. If you're sitting away from the unit, having an app makes complete sense, but if you're a desktop listener like me then you want the buttons at your fingertips and not having to reach for a remote or an app all the time. 🙂

This is an interesting topic and I'm still trying to get clarity on it myself. On one hand, the radiation used to transmit signals is at a lower frequency than visible light and therefore has less heating power as I understand it. Having said that, there is some evidence that people sleep better when electromagnetic radiation is minimised so it's probably doing something to the body. I'm still unconvinced in either direction on this one.

@nitraM321 Год назад

ok, so, i have one problem with the way you, and many others raté product, i think you should NEVER take price into account, if u do,u make many products appear equally great, when they clearly aren’t. even better would be if u had a ladder, and place the products at a spot in their ladder/ranking. the current way all of you do things makes it really hard to choose a product at a given price, because some 100€ product might sound so extraordinary in your review. think about it, and please send me the discord invite :) i would introduce a rating vs some representative headphones, or speakers, different technologies, hard, or easy to drive, susvara’, susvara’s and susvara’s :) oh and some speakers or amps, anything you have really, maybe someone should make a web site for that, right ? because without that all this information is just confusing i me a HOW am i supposed to chose between the Burson, KME, Ifi sigs, ferrum (try to text them) etc ? sounds like this one is better, and u clearly don’t mean that !

@PassionforSound Год назад

That argument cuts both ways, Martjin. If we rate it without considering price then it sounds like cheap gear is just as good as expensive gear and that's normally not the case. I think the best balance point is to provide comparisons with similar priced options, sometimes an option above or below in price and to discuss the unit's overall value for money rather than ignore price altogether.
