Coby,

If your goal is to create an "acoustic lens", then you probably want to use identical amps all the way around, or at least amps with the same circuit design. As I am sure you know, the phase/frequency response of amps can vary widely.
Absolutely. Intention is identical amps exactly for each level of driver, for all 7 channels. I'd love to use something like the Emotiva LPA-1 if it was actually a 7 channel amp instead of a 6 channel with the last channel being able to be a stereo amp at a much lower wattage.

I'm just starting the search for amplification. These will not be hard units to drive, since there will be no passive crossover. A rack of Audiosource amps might be an affordable way to go for the mids and lows, and still not sure about the tweets yet. Suggestions? I'm trying to keep the amplifier budget between $1500 and $2k tops...hopefully less. I"ll be scouring Ebay.
Gain control and balanced inputs would be a bonus.
