I tried the bookshelf speakers in the mix and just like I suspected, the noise is MUCH less apparent. I had the pre-amp's volume set to 70 (vs the 60 I used with the Fusion's) and even though I could still hear the artifacts when I put my ear close to the speakers, from listening position, its virtual inaudible.
One thing that is really bothering me however is I think the amp is turning off the outputs (auto muting or something) when there is no signal. It makes it very hard to test. Essentially when nothing is being played, all I get is normal "hiss" which is inaudible until you put your ear next to the tweeter. When music starts, you hear the annoying high pitch noise (almost a ringing, not a hum or buzz -- very hard to describe). The amp has 3 settings "on", "music" and "12v". Its set to "ON" yet when listening to a cd for instance, in between tracks, it goes silent and sometimes I loose the first 2-3 seconds of the track before it turns on.
Frustrating problem. My big thing is. I dunno if its a problem with the processor, a problem with the amp, or if its just the nature of a not so quiet amp design with efficient speakers. If I thought the latter was the case, I'd just list and sell both items and get a new Marantz receiver. As is, I'd feel bad about selling something that I'm not 100% confident in.
