Congrats davt, on your MQA feedback.
I’ve got the MSB Select II with the MQA quad rate USB also and have really enjoyed the MQA master files on Tidal. i have to admit i was a serious skeptic on MQA but no more. some of those files are very, very, good. I would generally agree with your descriptions. it’s a more musical, less ’processed’ type sound.
the quality does vary with the resolution differences; the best being the 192-24 and 352-24 files. my own higher rez files are also better.
i use the SGM server with HQ Player, Roon, and Tidal and it’s very seamless and easy to navigate.
