I just purchased an Audiolab CDT6000, but using Audioquest Cinnamon Coaxial into my McIntosh MA 12000, the CDs mostly sounded flat compared to streaming Qubuz/Roon via iFi Zen Streamer/iFi aftermarket PS and Cinnamon USB.
This might be a deficit in the McIntosh Coax/DAC, but the unit is going back.
