I recommend considering the harman kardon 3480, 120x2 @ 8 ohms

a) It's under $280 on amazon

b) It's much less than that Rotel(as much as they sound as good as they look: no way there's much audible difference between that and the HK, if even a measureable one)

c) The onkyo has no subwoofer or pre out outputs, which kills upgradeability. Sure, you can plug it into the speaker level jacks on the sub, but it just aint the same..

I was considering that Onkyo when I saw it on amazon refurbished for about $180. However, no sub output really sucks.
