...and I don't really want to go beyond this hypothetical scenario... 2 axiom amps - Amp 1, to run a left and right M80 and 4 QS8 surrounds (bi-wiring the M80's) - Amp 2, to wire 2 center channels Which would be the best scenario: amp 1 - have a y splitter out of the pre-amp into the amp for the M80's (in effect creating 2 channels for one), or wire in series/parallel out of one channel (ie, have a y splitter for the left and right and use the individual channels to bi-wire, or use one channel and wire in series or parallel) amp 2 - have 2 center channels and y split out of the pre amp and use the individual channels for each center. Is y splitting out of a pre-amp into an amp, creating two powered channels even possible? Signal degradation? If money were no object, would this be the best solution, or would wiring in parallel/series be the best option? Is a second amp really even neccessary? Can all this wiring be done with 1 amp? Just curious....I bought a lottery ticket and i'm feeling lucky

y-splitting is just fine, but I don't think a second amp is necessary at all. As I understand it passive bi-amping (which this would be) would merely give you more headroom. Do you really need more headroom when you've got 1400 watts/channel to work with?

I should have prefaced the post with the fact that I have no Idea what I'm talking about.
I was just curious what would be the best solution with the requirements ie:
Bi-wiring the M80's and running 2 center channels (possibly 2 M22's and 1 VP150)

Er... you don't get 1400W/channel. It's 1400W total that can spike high as per their spec sheet with 2/4 Ohms, but is essentially there to drive multiple channels.

Our friend Peakjunkie in Manhattan Beach, CA is running 10 speakers from his A1400-8. I can't imagine that biwiring or even biamping a pair of M80's would be more of a load than four M22's. 2 center channels (possibly 2 M22's and 1 VP150) Umm, that sounds like "three" Overkill, IMO. I think Ian and Amie have 2 VP150's (one above and one below). That seems about right to me.

Read the specs... Power (1 channel driven) 8 ohms - 350 watts 4 ohms - 700 watts 2 ohms - 1,200 watts

0 ohms = 1400
just kidding

That's still 3 center channels, as far as speakers go. Sounds like a good way to obviate the left and right channels.
In any case, 350 watts/channel on average should be quite sufficient headroom wise, as it is extraordinarily unlikely that all 8 channels would need to peak at the same time. At least, I wouldn't want to be in the room when that happened.
