Thanks Aaron. As a matter of fact, I wrote Peter @ Pass last night and will look for a reply early next week. I may just call them on Monday. I tried every combination of interconnects I can think of and still it buzzes. I am going to look in the Audioasylum archives on ground loops today to see if I can find any good ideas.
Buzz originating from amp...please help ?
I bought a Pass X250 through Audiogon and when hooked up to my system, a hum or buzz is coming out of the tweeters and midrange speakers on both channels. After exhaustive trial and error, I find that the buzz does not exist when the amp is not hooked up to any other component. It is of course connected to the speakers. If I attach a pair of interconnects to the amp (whether or not these interconnects are connected to the preamp), the buzz comes back. Does anybody have any ideas what I should try, or what the problem may be? Thanks for any imput.
