I have Panamax M5300 to filter AC noise and Emotiva CMX-2 to block possible DC.. Still buzz... Not very loud, you have to be within 1-2 feet from speakers to hear it, but it is there..always...
Sounds like McIntosh has a QC problem with this line. How are they letting those units out the door? For them to reply via email that a hum/buzz is to be expected (just the nature of tubes) is a blow off statement IMHO.

I feel bad for the members who trusted the brand and then have to put up with that annoyance. If it were me, I would have sent the unit back ASAP and demanded either a non-buzzing unit or a refund.
