Maybe I am overthinking this
You know, after posting here (you guys have provided great info) and reading posts from people who actually have the 1020, I have realized that I indeed have been over-thinking this. When I did the 5 channels driven calculations for the 707 vs the 1020 and 1120, I concur with the guys who stated the 707 has more power. But there were a couple of guys here that stated the power difference would not be noticeable; I concur as well. according to the specs of each avr, the 707 does 100w 2ch driven and the 1020 is 80w 2ch driven. With 5 channels driven the 707 does 40w ch and 1020 does 32w ch. Although the numbers prove the 707 has more power than the 1020, but by only 8w ch. I don't believe I would notice this. Now what I won't know, until I get the receiver, is whether 32-40w ch is enough to satisfy me.
Now that I understand this, I see the need for pre-outs. I will run the 1020 as 3.1 for now and when the 1120 comes out, I will return the 1020 to BBY and get the 1120 and an amp to run my surr. speakers. I would rather not share my fronts or center with any other speakers, meaning I would need 2 amps; one for the surr speakers and one for either the center or fronts.
Does this scenario Make any sense to you guys?
