Am I missing something? Bored in my hotel room and have been on the interwebs for awhile searching and can't find an answer. I have a Pioneer DV-45A>> SMSL M8A >> PAS2. It will play CD's great but put in a SACD and the SMSL says no signal. I currently have it hooked up via Coax. I haven't tried optical out yet. And I won't be home for another month to try. Maybe a setting for the DAC? Edit: Forgot some symptom recognition. Works from audio out RCA's.
