I'm having the same hiss and noise as the person describes below (he never got an answer here).
I have my ICBM connected between my Marantz AV9000 and amps. My cables are pretty good, I have my system connected to an Adcom line conditioner(except the ICBM). The ICBM stays on all the time. Through all the channels, I hear a hiss all the time, and faint clicking when I adjust the volume or change sources. Granted you have to be close (2-3 feet) to the speakers to hear but it is a little annoying. I'd like to keep the ICBM connected this way because the added bass management capablities improves the sound of my entire system. I'm pretty sure it's the ICBM. If I take out of the setup, the hiss.clicking goes away.
Anyone here or from Tech support help me out?
Thanks - Jeffer65


From Bensen98;
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
