HDMi 1.4 all around and no florescent lights. If I turn the speakers down to a lower volume, I can't hear the fuzz/hiss.

I just set up my audio system consisting of a Denon 4311 Receiver and Klipsch RF-7 II/RC-64 II/2x RS-62 II speakers. I ran Audyssey and then tried a Blu-ray on my PS3. When I have the speakers at a reasonable volume, there is audible hiss/fuzz coming from all of them. Is this normal, and if not, can it be corrected?

On the Klipsch RF-7 II, there are two sets of black/red speaker terminals. I was curious why that is and which row is better to use?

I'm going to soon have a complete RF7-II speaker system (2 RF-7II Floorstanding, 1 RC-64 II Center, 2 RS-62 II Surrounds, 1 SW-115 Sub). I was hoping to get some recommendations for a receiver/amp combo or receiver to sufficiently power these. I was thinking perhaps a Marantz AV7005/MM7055 combo. Would this be a good choice?
