I see the 770 is rated at 200 wpc with an 8 ohm load. What is its power output and compatibility with a 4 ohm load? I have a 6.1 setup now with a 1050 + SVS sub powered by a Peavey amp. If I go to a 770 later on, I would like to use the 7th channel for the SVS (which has a 4 ohm driver). My 6 speakers are 8 ohm.

Thanks... KJP
