+1, install a DC Blocker to see if that stops the hum. And, if not, Return the amp to your retailer ASAP. Please keep us posted. For example, please this link:
Or, maybe try a less expensive DC Blocker from your local hardware store.
Help! Is my new McIntosh MA12000 broken?
Hi, can you please help me?
I bought my first McIntosh amp, MA12000 and it is making a pretty loud hum.
It does not come from the loudspeakers.
The hum comes from the amp itself.
With or without any sources connected to the amp make no difference to the hum.
I`m a bit surprised that such an expensive amp is so noisy.
Do you think there is something wrong with the amp or is it supposed to make that humming noise?
Any and all answers are very much appreciated.

I had significant transformer hum from my small tube amp when I moved to a new residence years ago. Purchased the Emotiva CMX-2, which completely addressed the issue. Worth a try.
