John Curl-designed and THX-approved multichannel amplifier. 6-channel operation: 6 @ 135 wpc (8 ohms) 5-channel operation: 1 @ 300 wpc, 4 @ 135 wpc (8 ohms) 4-channel operation: 2 @ 300 wpc, 2 @ 135 wpc (8 ohms) Perfect for use in home-theater or multichannel audio applications... can be used to drive 5.1 system with passive sub or 6.1 system (since the rear center is mono, speakers can be wired in parallel to the same amplifier channel) with active sub. Consumer reviews of the amp can be seen here, and detailed specifications and manual can be seen here. Amp is in perfect condition functionally and near-perfect condition cosmetically. The unit is rated 8/10 (Audiogon scale) mainly due to age (it was purchased 3 years ago) and a small nick on upper right edge of faceplate. Pictures can be provided on request. I am only selling since I've been changing my system emphasis from HT to audio and am moving to tube amplification and high-efficiency speakers. Original retail $1950, asking price is $825 shipped. Payment will be discounted by $25 for payment via personal check, money order, or cashiers check. Amp ships following clearance of funds following payment by personal check.
