Quick Receiver Question!

[Jaren613]

Hey guys. I finally got around to getting something better than my HTIB surround sound solution. I decided on the following:

Def Tech ProMonitor 1000 (Front L/R)
Def Tech ProCenter 2000
Def Tech BP1.2X (Surround L/R)
Mirage Prestige S10

The room is about 10x18, but the problem is the whole left side opens up into the dining room and kitchen, so the actual room is much bigger, but the speakers will only be arranged in the living room section.

I was looking at either the Onkyo 707 or 807 as my receiver. I was curious as to how much a difference 100w/channel vs 135w/channel (at 8ohms) would make in my room, and if I even needed that much power.

The other thing is right now I can find the 807 for just $100 more than the 707. I don't think I will really use any of it's features though (other than the extra wattage).

So, is the extra 35w/channel worth the upgrade? Also any suggestions or improvements on my setup are welcome. If there is a more suitable amp in that price range (under $1,000), I'm open to suggestions as well.

Thanks!
