My set up is RTiA7 fronts, CSiA6 center, and RTiA1 surrounds, with a DSW micro pro 1000 sub. I have 2 receivers to pick from.... I have a Denon 2309CI and I have an Onkyo TX-SR806. The Denon is 100watts per channel and the Onkyo is 130watts per channel. If I go with the Onkyo, the A7's are good to go as is the A6. But what about the A1's? Their suggested range only goes up to 125watts. I am thinking since they are used for surrounds, it would be OK. Needing a little direction from somebody that knows. Thanks.
