Got the m-60s hooked up to a Crown k-1 amp. The mains sound fantastic. It is really nice to just let the 60s jam in direct dode, no sub, no nothing with right material. Now when I shut off everything, and the Crown is on (both ch.1 and 2 turned all the way up) I get a decent buzz in the mains not real bad, but apparent. Also now when I change channels on my sat receiver (samsung 360 HD) I get a little pop in the mains, each time it locks in on a channel, not louded just annoying when surfing. Is this a grounding issue, any other thoughts??

Jon I also notice a "pop" once in awhile when I change channels on Sirius on a dishnet sattelite. Only on the sirius channels though.
I wonder if frequency (certain channels) has any thing to do with it?
