Hi avguytx, Im the person who bought the Carver m400a cube amp and the nad preamp. I ended up using a Precision Power PC2150 car audio amp for home audio so the Carver is being sold. Its on audiogon right now, but if it doesnt sell there (150 starting bid) then I will sell it to you for 150. I was told by the seller that it was stored in a 68 degree room year around for 15 years never used til I bought it. Could use the refurbishing as it makes the fast clicking sound that all carver cubes do. However, since I bought it it works great, sounds great and has not given me any problems. I can give you a link to the auction if you would like. -Keith
