Pretty sure @JohnYang1997 would tell you what that error code means as he is the designer of the A90/A90D. But if you don’t get any response from him, I would definitely contact the dealer and ask for a replacement.
Got the A90D on Monday. Yesterday, I was experiencing random LOUD pops from my right powered speaker connected via xlr out. They were intermittent and sporadic (maybe every minute or two). A few of the pops also produced a fault code of “-5” on the LED display. It is connected to RME ADI-2. Coincidentally, when I first opened the unit and plugged it in, it showed “-5” and would not function/operate until I put batteries into the remote and pressed a button, then it went to showing volume level. Any clues from anyone? Is this a faulty unit? Should I try the firmware update? I’ve gone back to my previous amp in the meantime, don’t want to risk blowing up my LCD-5’s..
Update: I just plugged it back in and tried powering it on. It is giving the same "-5" fault code, but won't let me get past it now. Previously for some reason putting batteries in the remote and pressing a button on it made it start working, but now it is stuck on "-5" on the LED display. Seems like I got a DOA unit, going to reach out to Apos to get a replacement.. @JohnYang1997 If you could still give some insight on the '-5' fault code and what it means, that could maybe help debug the issue for other units
I'm curious is there any benefit to running this balanced with the DCA Stealth and RME vs just using the RME out? Assume average listening level of 75db. Sometimes more.. sometimes less. Or is it if I listen at the same volume with both devices they will sound virtually identical even given the different amount of current provided by each device?

This is a review and detailed measurements of the just announced Dan Clark Audio Stealth closed back planar magnetic headphone. Company was kind enough to share with me a couple of samples which I have been testing and playing with in the last couple of weeks. It costs US $3999. The price...

That is what I figured, but I know there was an audeze article that talked about small transients that could be louder even if we don't perceive it on our ear as that loud and is non damaging to our hearing. I'm absolutely not making a statement of fact. But I know technically speaking the RME might not be able to meet the requirements of those sounds if true and I do not know the effect.

I have been using my everyday Dan Clark Stealth headphone as a "it won't drive it but let's see what it does" test for headphone amps. This is the first time I have seen an amplifier have such an upper hand over these headphones. The sound is incredibly dynamic and beautiful. "Loud" listening is at volume level 80 in high gain. I cranked it up to 95 before I got scared for my hearing without any hint of distortion. I had not heard these headphones come to life so well.

Yeah I read the review, I was interested in an actual comparison if there had been a difference besides just being able to damage hearing without distortion

It is a direct comparison with the RME. @amirm has said that the RME is his every day dac/amp. When he says he has never seen an amp have such an upper hand that includes the RME. When he says he has not heard the Stealth come to life so well, that includes compared to the RME. What exact comparison are you looking for?

I just took delivery of an A90D. It is my first topping product. I am using it as a preamp. Seems to function as intended so far. Its had music going through it for 24 hours. No problems. I have a schiit freya s it might replace. I like the volume display. The clicks are almost silent compared to freya. With my sons help I will do a blind comparison between 2 at some point.
I have an Asgard 3 (discrete design) and have paired with D10s (ESS 9038q2m) and E30 (AKM 4493). I like both pairings but seeing as Asgard 3 is warm sounding...I'm finding that D10s is the better pairing due to ESS is the more analytical sounding of the two DACs but this is just my subjective opinion.
I recently received an A90D, and I'm quite impressed with its sound. However, I think there is some sort of bug. The amplifier automatically shut off when I unplugged the headphone connection from the 6.35 mm output. So, whenever I switched headphones, I had to turn it on again and again. But the amp continued to turn on after I removed the headphone connector from the 4-pin XLR output. I want Topping to update the software in order to fix this problem.
