The Roon streamer function. Mini-I Pro 3 is also a headset amp, D90 noWill I get any advantages of A90 + D90/MQA combo vs A90 + other non topping DAC (Matrix Audio Mini-i Pro 3) ?

Low and Medium gain both have lowest distortion possible. If you reduce dac volume you lose dynamic range though.
Tldr just use low gain if its loud enough.
PS: my Harmonicdyne Zeus are already pretty loud at low gain 9 a clock, thats when you can actually turn down dac a bit so you dont run into channel Balance issues at the start of the potentiometer.
probably I was not quite clear. I just want to clarify - if I use any none Topping DAC with A90 will I get some "penalty" compared to A90 + D90The Roon streamer function.
A90 already has headset amp. Is there any sense/advantages in 2 headset amp in such combo ?Mini-I Pro 3 is also a headset amp, D90 no
ground loop through pc usb. use xlr and issue will be gone.I seem to have EMI issues when using the Topping A90.
My audio chain is:
Computer USB --> ifi iDSD Signature RCA out --> Topping A90 --> Neumann KH80 active speakers OR headphones/ IEM
After the addition of the A90, I clearly hear background buzz over all outputs (both RCA and XLR to speakers, both balanced and SE headphone out) which gets stronger when my computer's GPU is working harder (like playing videos or loading apps).
One interesting point is this phenomen remains the same when the iDSD Signature DAC is turned OFF, and only the A90 is turned ON.
Before I had the A90, the ifi iDSD Signature feeds my IEMs/ headphones/ speakers directly and the background was nearly silent, though I can detect more "hiss" when playing videos (with the video player volume at zero and the headphone out of the iDSD turned all the way up), but nothing as loud as when using the A90.
Any suggestions will be appreciated! Thanks.

I assumed this design allows better SINAD. I think all the best performing DACs and amps are class I.design their low-power components (DACs, preamps) as class I components with signal ground connected to mains protective earth
exactly. Maybe some additional features which are not available in A90/non Topping DACYou mean if there's a synergy between A90/D90?

In my case I eliminated USB ground loop hum and interference by changing the power strips my devices are connected to, so in my case the PC, monitor, router, and external hard drive are connected to power strip A, while the DAC and amps are connected to another power strip. No interference.
I don't think so. It's just a good idea for them to have surge protection. In my case I have the two power strips plugged into two sockets of one outlet.Any specific requirements for choosing your power strips? And your strips use two separate mains socket?
I have a cheap six socket strip plugged into another six socket which goes into one mains socket in the wall. At first, I thought using only one wall socket for all my computer and audio equipment would give me less ground loop problems, but now it seems not to be the case.
Why not D70s instead of D90?Being lazy not wanting to go thru 100 pages; anyone using D30 Pro and A90 stack? How's the sound? I would rather use the D90, but of course, unavailable.
Why not D70s instead of D90?
As far as I understand D90 based on AKM 4499 and D70S on AKM 4497. Is there any valuable difference between those chips ?Why not D70s instead of D90?
