I do have an AVR paired up with a 2 channel amp for my mains. I'm letting the Arcam AVR power my center and rears. I'm wondering now if I should have just gone with a 3 channel Amp up front like the XPA-3, as opposed to the XPA-2, but the 2 is a beefier amp and my 802's like power.
I'll switch all my speakers to small with an 80 cross over and see how that makes everything sound. I will however, keep my speakers at full range for stereo though, as I much more prefer this.
In terms of the DCX, I guess I'm going to need to buy another Amp for my center channel first...
