I'm trying to make up my mind on a 5.1 setup. I had been looking at M60's/Q8's/VP150/350 sub for my 15.5x20' basement theater. I would drive that system with a Onkyo NR1007 (maybe 3007). But looking at just a little more money for the M80's has me thinking. It seems some people think the Onkyo would not be a good choice for 4 ohm speakers. The manual says it can, but says not to do it for long times at loud volumes.

My dad had a patched up system with several different speakers, and I'm quite sure he never really set the amp up right, but every time a movie got loud (explosions, etc) the protection circuitry on the amp would kick in and kill the sound. I don't want that.

I can stick with the current setup, I think it would be plenty for my room, but there's always the upgrade itch too, and maybe a little more up front would go a long way, or maybe not.

What do you guys think?
