I have been using an Outlaw 7500 on my 8HT-LP's, but just took it out of the system temporarily to do some testing in another room with some speakers. It got me thinking, do I need the Outlaw 7500 if I were to upgrade my processor to a receiver with Audyssey xt32 (Denon 4520ci or Marantz SR7008)? I have been wanting to upgrade the processor for some time, but still waiting for a xt32 processor in my price range - hasn't come around yet. Also, the Outlaw does have some hiss feedback through my JTR. Maybe I can sell the amp to fund a new receiver and maybe come out ahead after selling the processor and Antimode as well..
I'm running my S8-HT's (LCR) and S8-LP's (surrounds) all off a Pio SC-35. I watch everything loud, at reference or slightly above and I've honestly never heard the amp clip, had the amp shut down or even heat up much for that matter. I also cross at 80hz and let my dual S2's handle the rest. I don't play a whole lot of music but I did the other week and was playing at +3MV with no problems. In fact, after about 3 hours at those levels everything was just cruising along. Hell, I felt the amp in the AVR and it was just warm to the touch.
I think, IMO, people start running into problems when they have much less efficient surrounds than their JTR mains. Running at those levels with some 89dB surrounds would tax the amp in most AVR's pretty quickly.. not to mention you'll most likely be wearing the tweeters.
What are your listening habits? Movies or music? Is this a 5.1 or 7.1 system?
