Sorry I can't really answer your question but I have a NAD M2 and I had PSB Synchrony Ones for a week and this was the most horrible sounding pairing I ever had the displeasure of hearing. The PSB are great speakers and the M2 isn't a bad amp but synergy just wasn't there.
The question is how close is the M2 to M12/M22 combo?
