Having an issue with the Q11. As I'm playing various music from Amazon Music, the bit rate will change from 192khz (or 384 if thats what i set) to 352khz on the Display, and the sound will sound very tinny, and muffled. I then have to cycle through the optical, and coax, to get back to USB, to fix the issue. I'm usually in AKM mode, have yet to test if this issue is repeatable in the ESS mode. I have tried 2 units to and am experiencing the same bug.
I could be wrong, but it seems like its almost like some kind of protection kicking in.
It could be my pc, however the SMSL-SU1 doesn't do that, and neither did the Aiyima DAC-A2. I also recently (2 days) did a fresh reformat of windows 11 pro.
