Following up on my own post..I purchased a D50 in May 2019
My D50 has developed a channel imbalance (left channel louder than right) when using USB.
The problem does not exist using TOSLINK from the same motherboard. I tried my old JDS O2 DAC via USB with no issue.
So the problem appears to be with the D50
I'm talking to Topping about the issue...
Yes, USB only.
There is no balance adjustment on the D50. The issue seems to be in the difference in signal paths, USB vs TOSLINK internal to the device.
I'm running Linux and made no changes to my config when changing USB DACs, so I don't believe it is the audio chain on the PC
So what did you do wrong that caused you to think there was an issue. No embarrassment need be felt, we're all human, we make mistakes. Admitting error and learning from it, and even helping to prevent others making those same errors, that's nothing to be embarrassed about.I need to retract my post above regarding a balance issue with the D50...Embarrassingly, the problem was entirely on my end.
There is no issue with the D50
