why is this thing humming?


I just hooked up my new mcintosh 207. I made sure the cables arent bundled and what not everything looks pretty clean. But this amp is humming something bad. I rehooked up my rotel 1095 no hum what soever. This is up setting since the reason I bought this amp was the Rotel was supposed to be the wink link. Please help I need my tunes up and going.

Rich thanks for the input Ill give it a shot tommorow thatll be the first thing on my to do list! Ill keep you posted.
Don't forget to eliminate humming (buzzing) of power transformer. Humbuster may work in that regard.
Im sorry I may have not given enough info. The hum is coming from the speakers it isnt as apparent after the music is being played at moderate levels but I dont think the hum goes away. Matt
Matt, be careful with cheater plugs I put some in and the system was dead quiet but it strangled it sonically. I have Mac 501's and they send a small hum to the speakers and it varies from IC to IC but it isn't enough to be a problem for me.
