Merkles: I am currently running a 1050 with a Parasound 2ch. power amp rated at 205wpc. I see no reason why you couldn't do something similar with the 1070 if only your mains present a difficult load. Depending upon your needs you could also look for what I assume will be a greater volume of 755's on the used market.

Frankly, while I would like to upgrade to the 990 and a 770 or its replacement, my fall back is to just replace the 1050 with the 1070 and keep the Parasound for the fronts. Currently, my biggest problem is being able to justify to the better half why the 1070 is $500 to $600 better than the 1050 for a 6.1 system. Anyone have any suggestions (Dolby Headphone alone probably won't do it)?
