Excellent condition and rare MF5600 five (5) channel amp. Unit just back from CJ with clean bill of health. It includes the all important cap update. There are a couple very light scratches on the top panel. The top edge of the front panel has a few very tiny dings. You cannot see unless you are within a foot or so of the amp. Try to find on pics. Have you ever vertically bi-amped? You can use 4 channels to drive both the bass and mid/tweeter for improved sound on your two channel system. Your speakers would need dual input binding posts. Just remove the jumpers, and hook up amp. If your preamp does not have two sets of main outputs, use a "Y" connector. Included are all factory crating, power cord, and a copy of the ops manual. Unit will be double boxed for save shipment and protection of the factory crate. I will pay shipping/insurance, in lower 48, at asking price.
