Topping A90 Review - Mr Clean would be proud

[@subbot8077]

I've gotta say, I started with your Chord Dave/M Scaler review and you've quickly become one of favorite audiophile equipment reviewers on the platform. I love the Zeos-style headcam, I love that we have similar music taste, I love that you can present important information in casual/easy to listen to manner, I just love this. Cheers, and I'd love to see your thoughts on the Gungnir Multibit and Mjolnir.

You should totally keep the reviews up. You could potentially run half the YT reviewers out of business.

Just found your channel and it is very descriptive and communicative . I’d like to add even though I loved my topping D90 mqa, after 4 months it flickered and simply died . It came back for a second but then zilch . As a warning buy this from an American distributor because to return it to China it cost $130 Canadian to get there in 10 days , $80 to take 3 months . They would allow any other way . Usually my China dealings are amazing and positive . Simply take this into consideration. My A90 is still great .

This is probably the best review of the A90 I've seen. However, I think it was unfair to compare this amp with the Modi, IMO it should have been better to compare against the Jotunheim 2, as they are in a similar class and price range, so it would be more interesting and useful for potential buyers (like me, *wink*).

Great reviews, the first time i hear a reviewer mention null testing (magnius video) and that the measurements on ASR are too limited to tell the whole story. Although those measurements do show if something is is objectively altering the sound in even the simplest tests (like a sine-wave).

I'm glad I've stumbled upon your channel. Currently looking for my first set of equipment (DAC + Amp) to drive my headphone(s?). Still have to listen/chose between Focal Celestee and Hifiman Ananda. Perhaps others. Watched a couple of YT-bers and wandered through forums. First I thought about the Bifrost 2 as a DAC combined with the Jotanheim 2 Amp as some say the multi-bit-card in the Jotanheim is ok-ish but the Bifrost 2 is much better. But.... based on price alone it got me thinking: is the Jotanheim 2 the correct Amp for it? The same YT-bers really like the A90 and you just said the A90 sound beautifully with the Bifrost 2. Thanks for that!!

[@BillyKueekSG]

I bought the A90 & D90SE stack, purely based on reviews and in some parts, due to measurements. My warmest headphones can’t work with the stack, several were too bright and “piercing” for me. So I put both on sale, the D90SE was sold to a gentleman who uses it with his “warm” floor standing speaker systems and he loves the clarity and details. The A90 has not found a buyer yet but I’ll be ok to keep it to pair with warmer DACs and to enjoy music with my warmer headphones. Now, even my bright headphones do “ok” with it. If I can’t find a buyer, I’ll just keep it and use it this way. Cameron, I connected with what you said about measurements doesn’t if my ears disagree in your video chat with Lachlan. Are you planning a Gustard R26 review soon?

Great summary of the product, thanks

[@Ali_Shafai]

I just discovered you and subscribed and I find your review style fantastic. 😀 A personal education question: I noticed that you have an XLR to single-ended adapter. Is there any disadvantage or shortcoming in going from balanced to single-ended via an adapter, when one has to, from a performance or fidelity perspective?

[@GoldenSound]

Thank you! It is totally fine to go from a single ended output to an XLR input/device. (eg: SE amp to balanced headphones like I did in the video, or from single-ended DAC to balanced amp). Though provides no fidelity/sound benefit. Its just handy instead of fully swapping cables. It is NOT ok to go from a balanced output to single ended (such as balanced amp output to single ended headphones, or balanced dac output to single-ended amp). This can damage or break the source device either instantly or over time as you are shorting it.

Hi, i just found this channel because of the MQA story and also found this review, which was interesting to hear. I had a sabaj d5 at home one andalways thought good measure tech would sound the same and it was for me for a lot of amps, couldnt not tell them apart (Headphones Hifiman Arya). But the sabaj d5 was super harsh and fatiguing, i had to stop listening after just 10min., never happend to me before. I had not the chance to just listen to the DAC or Amp alone, so my question would be, what could be the cause for that? The difference was so huge, that it left me speechless.

[@andjeyvolikov3508]

@GoldenSound thank you for review! From your point of view, if i already have A30 pro and d90 dac, is it worth to change a30 pro to A90? There will be sound quality increase? D90/A90 stack looks beeter than D90/A30 pro, but interesting what it will be in terms of sound? My case is: dac connected to the amp via XLR and headphones single ended from amp. Thank you

You mentioned that they are amplifiers out there that can deliberately smooth out harshness (sibilance test #2). What are some of your recommendations under $1200-ish ? Thanks!

[@TheCangle]

I just did the sibilance test and got interesting results. My chain is allo streamer -> ADI-2 -> Flux labs FA-12. With the LCD-4z I could hear what might come across as sibilance on both tracks but the cymbals with the vocals on the first song didn't bother me and the second song wasn't bad either but it didn't sound great. It wasn't really sibilant it just sounded kind of edgy I suppose. Then I switched to the 800S and the first song was fine again and the second song was worse. I could hear the sibilance but I didn't cringe as much as you did in the video. Maybe my gear is smoothing things out or my high frequency hearing is just bad.

[@RyuMasterEX]

Fa-12 doesn't smooth out treble, it was similar to the a90 but slightly less edgy. The fa-12 is gooey, firey warm yet not rolled off which is magical. The a90 is like a straight line, made of water nothing sticks out and errs on the thin side sometimes but nothing like the 789

[@ergoproxy6998]

nice review , i just bought a topping a90 + chord hugo2 + ifi idsd signature ,and hd800s + arya (i think i will buy a clear in the near future ,maybe a diana v2 later ) i will try them all for a few weeks then keep what i like and sell the rest ..... where can i buy cables like yours pls.

[@simianinc]

I bought the Modius and the Topping a50 (which I’m told has a similar house sound to the A90).

[@arefinkhandaker4370]

my very first audiophile amp dac journey started with fiio k5 pro and theres a ton of great reviews about fiio k5 pro on youtube as well. But in my experience, they are overhyped, yes they have details but cuts the low end fun from the headphones, sibilant at times, and i dont know much about soundstage yet! Do you think i'm going to notice better sound performance on these a90 if paired with any decent dac? Do you feel like topping a90 does cut the low end fun from the headphones as well? Do you think ifi micro idsd sig would be better option for me if im looking the low end fun sound to stay there with my headphones?

[@blanchbacker]

Listening on Arya I could definitely hear the difference in the low end with A90 balanced vs SE

[@GoldenSound]

Arya scales quite a bit with more power. Even on a speaker amp it gets a bit more oomph. But other than power, and speaking strictly in terms of SQ, the se is just as good. Balanced will of course have more power which for planars in particular will be a benefit

Would they benefit from an upgrade to the A90 and maybe a D90SE stack? Do the LCD Xs get the same benefit in the low end from more power as say something like the Arya?

P.s. Amazing review. You are the best reviewer by a long shot

[@satyaprakash3098]

How can speaker amp or 6W power improve sound of Arya? Is it actually taking that much power? Do these have Hugh variation in their impedance across the frequency.

[@En_Joshi-Godrez]

Some planars need high current because of the voltage sag due to having low impedance, but also low efficiency (like the ayras). Low end Chinese amps from the likes of topping and smsl will make them sound loud, but suffer from heavy compression due to not having the capacitance to offset the voltage sag. Speakers amps offer much higher capacitance than most headphone amps (expecially for the cost) at the cost of noise, but most modern amps are low enough that they are practically inaudible with headphones. Dynamic headphones can be run off anything that will get them to your desired volume because they are almost never low impedance AND low sensitivity, so no voltage sag.

[@joosteijkenboom1988]

I don't think HPA4 is good value for money and didn't really enjoy it when I tried it. The HPA4 is not a ~$3000 headphone amp. It is a $2500 preamp (LA4) with a $500 headphone amp module (THX 888) added on. To me it basically sounded like a slightly improved 789. It was still too cold/clinical. The AHB2 I much preferred the sound of overall, and with susvara particularly the difference was very obvious, the AHB2 handles them wayyyy better. The AHB2 in my opinion is a much better amp so long as you're happy to get a preamp

couldnt you theoretically get the a30pro if you wanted what would be a cheaper a90? Since it looks more like an a90 but without the pre-amp feature..

Possibly, my concern with the a30 Pro is that it isn't actually balanced, so it's more like a beefier l30 to be honest. But with 5w of power anyway, the need for balanced is somewhat debatable I suppose
