So, in the end, the audio sh*t you are decribing happend only when playing MQA, right?I heard about the SU-1 and wanted to check it out myself, so I decided to purchase it.
As rumored, the sound quality is incredible considering the price.
I checked the USB/COAX/OPT input by randomly switching between PCM44.1~768kHz 16/24bit and DSD64~DSD512 files, and the playback operation was extremely smooth and stable. There were no worrisome movements or habits. The workmanship is unbelievable for the price.
The difference in sound quality with higher-end models has become really small.
MQA playback is smoother and more comfortable with the USB input than any other DAC I've tried.
However, switching to COAX/OPT input will result in poor operation.
The beginning of the song is always cut off, which makes me feel strange.
Also, if you stop in the middle of a song and play it again, the sound will come out once and then cut out for 1 to 2 seconds.
This also occurs when changing the playback position. Well, I don't use MQA for COAX/OPT input, so I don't care.
So, yes, everything is fine with your setup, as nobody cares about MQA. And if someone still does, then may burn in hell.
R.I.P. MQA, once and for all.
