As long as you get a decent subwoofer the 1070 should be fine, as it won't have to drive the deep lows in a movie. [i.e. explosions] besides if it turns out it's not enough for you, you can always and seperate amps to it.

As far as other suggestions, i've always been a Harman Kardon fan so the only one in your price range that has digital switching that I would recommend would be the h/k avr-7300. It can be bought direct from harman kardon on ebay for under a 1000 dollars.[refurb. w/2yr. warranty]

I have the h/k avr-635 right now and can't wait to compare it to the 1070.
