yes, it should do the trick, but you can do this while your player is in dap mode also. enable line out mode if it has one or go to highest volume on the dap.
Awesome, thanks!yes, it should do the trick, but you can do this while your player is in dap mode also. enable line out mode if it has one or go to highest volume on the dap.
Found a discussion regarding this in the official wm1z/1a thread, double-amping seems to be of a non-concern in any way for this DAP.Awesome, thanks!
As for running in DAP, I'm a bit worried about SQ decrease, because outs from the dap will probably get double amped this way... not sure if it's a concern though.
Could you please comment on that custom knob you have there in the A90 please? what is the size? was it difficult or just like any other removable knob? thanks again!!That's a TOP stack NoICE!
I'm really enjoying the HD820 with the Topping A90 Head.Amp... Prefer it to the Master 9 that's built-into my NOS11... It's very close, but feels like that A90 edges over it in terms of speed for me.
I prefer knurled metal volume knobs... no effect on the sound, of course, but does have a much more 'premium' feelno news still about the knob swapability????? thanks again!!

I have just sold my A90 tho (hope I don't regret it)
Just pull the stock one out; straight-out. -- If you're like me, getting a grip may be difficult with rough and dry hands; so a chamois cloth or similar.Can you please tell us more on how to swap the knobs out?
Excellent, thank you.Just pull the stock one out; straight-out. -- If you're like me, getting a grip may be difficult with rough and dry hands; so a chamois cloth or similar.
The replacement I used was from GoodComponent/GD-Parts; that has a hex-screw that you tighten
Hope that helps

Nooo!, that's a good way to permanently damage the Topping A90 potentiometer and then need an RMA back to Topping in China to get a new one.Excellent, thank you.
https://www.audiosciencereview.com/...-headphone-amplifier-review.13592/post-433435The removal process could have degraded the pot further(I'm very certain it has, and again with reinstalling). (Also the pot is fully customized, you almost are not able to find exact replacement for the pot, 5k 4gang 5% -60db tracking) So this is not recommended for everyone else. Also as I posted earlier it's clearly described and explained. It is the pot itself. But it's caused by external forced applied to the pot during the knob installation process. Some ended up requiring less force some with more. So the end result is some units may exhibit this behavior. But like many others have said, it's acceptable and doesn't affect the performance itself of the volume control.
Many thanks for a useful intervention ..Nooo!, that's a good way to permanently damage the Topping A90 potentiometer and then need an RMA back to Topping in China to get a new one.
Just live with the knob - it's actually the pot that's got a loose shaft on some of the units that happened by forcing on knobs in production!, sheesh, it's an awesome unit as is, no need to try to customize it and ruin the Custom pot - user irreplaceable - in the process, from ASR:

Please read the posts by @rigel - he also posted photo's.
Lots of good info about the A90 in that thread and in the D90 thread. Great site.
John worked on the A90 and knows what's what with Topping headphone AMP's. I'd recommend if you want to figure out what to do with your knob / pot displeasures, create an account on ASR and ask John how to solve them safely.
You can't hear above or below that range, so does it really matter?Its frequency response say 20-40khz, does that means it can't amplify any signal below or above that range? Like if a deep 15hz rumble came on, would the amp even play that? Or is 20-40k just the range it specializes in primarily, but CAN go beyond?
