So I can't really tell what the difference is between the XPA-5 and the MTS-2 (aside from the 2 extra channels).
I currently have an Ovkyo 905, but might need more power for my new Paradigm Sig's coming in March. I was thinking:
Onkyo 905 - pre-pro, and rear-surround amp
XPA-5 fronts, center, and side-surround amp
Does that make sense? What about bi-amping the fronts, would I just split the RCA cable from the 905 pre-outs to two amp inputs on the XPA-5? So:
Onkyo 905 - pre-pro, rear-surround amp, side-surround amp
XPA-5 bi-amped FR/FL, single-amp center
Does that work? For $800 and the apparent quality, it seems like a great way to give me the increased power to at least my front speakers? Or am I crazy?
