Folks I am impressed. I have been purchasing audio equipment since the late 70's and this is the first time I have been impressed. A piece of equipment that does what it is supposed to do without any additional side effects. Saturday night I finally got a real chance to listen. Spent my day at a drill meet with my drill team and Color Guard, total waste of time as it has been for so many years. Stressed out, tired and sun burned I was ready for some relaxation. I put Transformers 3 into the player, kicked back, and just watched the movie. Overall the movie is just that, a movie. But the sound track really rocks. Having equal amp power to all channels certainly made a huge difference. With my previous set up only having an amp to drive the mains the center dialog was weak and surround was almost non-existent. Well that has all changed. Normally I listen at 20 db (According to the volume control on my receiver. What that is in real life .... Anyways, that is where I started and stayed all night. I did have some concern that I would blow a speaker since the surrounds are not rated to handle that amount of power, but all was fine. My impression of the amp is better, wider, higher, fuller filling, and best of all, quite. Not a stray sound as I have experienced before. One the movie was over, and I was ready for some sleep my last test of the amp was to feel the heat that had been produced by me driving the amp for such a long period of time at high volumes. The amp was warm, barely. My receiver was hot, once again. Not excessively but I could tell it had been running. Still can't figure that out since none of the amplifiers are being used.

My Onkyo also got pretty hot even while using it as a pre/pro to my XPA-5. Hotter than the XPA which as you said was just warm. I think it had something to do with the video circuits in the Onk.

I guess that makes sense. Overall the receiver does a fine job doing what it is supposed to do, even though it is older and does not provide all of the surround sound fields available.

Well you only have to look at the space allocated in a receiver along with a shared power supply (usually) and compare that with an amp filling a large case with boards and heat sinks separated for better cooling and a dedicated, and massive power transformer. No comparison. In all fairness, receivers have come a long way and the engineers that design them squeeze some remarkable performance out of them within the constraints they work with.
