I'd consider one of the Class-D multi-channel amps from Wyred for sound... they will be significantly lighter, much more energy efficient, and will likely sound as good or better than any of the amps mentioned above.
They have a model that offers 5 channels with 221 Wpc into 8ohms or 368 Wpc into 4 ohms for $1999. Unless the other power-hungry amps or the aesthetic appeal of the McIntosh is worth another $5000, of course...
