Any of you A90 users have any success pairing it with the Denafrips Ares II DAC?

I've heard of plenty of people using these together actually.

Am sorry then. I must have break the rule since I simply say...

Hi all, can this be used as by-pass output for RCA and XLR to another headphone? Thinking to daisy chain this between another headphone amp and didn't want to use it as preamp... thanks otherwise i have to keep changing the cables.

No. A30 Pro and L50 have bypass outputs(only, no pre-amp) but the A90 only has pre-amp.

I saw this has a listed frequency response starting at 20hz..?

Does this mean it can't play below 20hz?

Was thinking of running it with some Audeze planars that can go flat to half of that and I listen to EDM which does go that low..

I don't know for sure, but my findings when I had the A90 was that I was shocked how good bass was on the Burson soloist 3xp compared. Sold some gear and upgraded. The A90 is a really nice budget amp tough, but if you have the cash go for Burson Soloist 3xp. I listen to a lot of electronic music that goes deep too.

How much power does the a90 put out at 110ohm?

Also, does changing gain from medium to high change how much power is available at the same Db level? Or is it purely just shifting the volume dial around

This is a great 1st or 2nd step starter amp.

Funny coincidence, my A90 went kaput yesterday. It developed this loud crackling and popping on all outputs at any gain and volume, whether it's connected to a source or not.

I purchased mine on October 2020 from Amazon (shipped by Amazon but the seller is Aoshida HiFi-US). I contacted the seller to see about warranty service since Topping advises to contact the seller first. I got a timely reply but they ask for some weird stuff like to take a video and send it to them. Video of what? It's an audio defect. My detailed description should be enough. We'll see how it goes.

I just had the same thing happen to me now. The amp was playing on low volume using my Audeze LCD-XC headphones. The headphones were laying on the carpet, and I accidentally bumped the headphones with my foot. All of a sudden I started hearing loud popping sounds come out of the headphones. I scrambled to turn down the volume on the amp, but it didn't do anything, so I shut the amp off.

I've tried a few different experiments like switching out the DAC feeding the A90 (still popping sound) and trying the headphones on a different amp chain (popping sound disappears). I contacted Topping customer service this morning...

I was crapping my pants because I thought I ruined the headphones, but so far they seem to be okay...

I have the A90 and I love it, it was the first amp I have listened to that made a huge noticeable difference when listening to my HD650, I didn't know amp/DACs could do what it did. Unfortunately due to money constraints I have either had quality headphones and lower quality amp/DACs, or now a decent amp and lower quality headphones,.I hope to match the quality of both some day How does a Burson improve upon an A90 say, what does it do to the experience?

Yes I used it. Any particular issue you faced?

No Sir. I read a thread where some were discussing impedance mismatches between the two. I had no such issue. It seemed to work just fine for me.

Hey all. I got an issue if anyone can help or chime in with similar stories…

I got the D90 and A90 as loaners from Apos, for my YouTube channel. I’m sitting here ready to give my impressions soon in a video, and I’m finding that there is a significant amount of distortion on my HE6SE. Sounds like whenever I increase the volume to a certain point, the drivers can’t produce clean playback anymore. I thought maybe my headphones had died. So scared!

I tried keeping the D90 DAC in the chain but outputting through my Xduoo TA-30 hybrid tube amp instead, and that one actually had no issue whatsoever. So it turns out that the culprit in my setup is the A90.

Here’s the exact chain with the issue (so far; haven’t tried other interconnects and inputs)…

MacBook Pro > Usb C to USB A adapter > D90 > XLR cables from the Straight Wire company > A90 (high gain) > 1/4” single ended output > Hart cables (balanced, but balanced cables can go into single ended outputs just fine on my TA-30 amp) > HE6SE V2 planar magnetic headphones.

Again, the only change I made to the chain, to get lean sound again, was to go from my D90 to the TA-30 (via RCA). Otherwise all connections and so on are the same.

Anyone get issues with clean playback of their A90 at high volume?
