Wyred4Sound MC4 4-channel amplifier. Has two channels @ 250 watts and two channels @ 100 watts, this was a custom configuration for bi-amping speakers. I use this for my home theatre (I do not use a center channel) - Newform R645's in the front, PSB 10's in the rear. Selling only due to downsizing. The chassis has room to hold up to 7 amps, these additional 1-3 channels can be either 100W, 250W, or 500W. Very energy efficient and great sound, definitely the best amp I've ever owned. Discontinued but was $2,500 new. Unit is in Richmond, B.C. Canada. I have the factory box and manual. $1,500 + shipping.

Similar to this one except 2 @ 250W instead of 3 @ 250W:
