I hooked up my ICBM to my Marantz SR18ex through the Preamps In/Outs. Now whenever I change inputs (ex CD to TV) or turn the volume all the way off I get this thump/pop noise out of my speakers.

I was wondering if anyone else had this problem or knows of a work around. Its not a loud noise but I still am worried that it is doing damage to my speakers and it is annyoing.

Thanks
