Hi John, I will get my Cyrus 82 DAC Integrated Amplifier upgraded with QXR DAC Card https://www.cyrusaudio.com/products/qxr-upgrade-card/ and connect with my ROCK Server directly via USB, what can I do to update my ROCK server ALSA driver in order make ROON fully support PCM 32/768kHz and DSD512 format natively? as I found no Cyrus in Certified Partner list, Thanks for your advice!
