Audio Research Reference 75. Excellent condition. Comes with a full set of tubes (KT120 and 6h30's) purchased from Upscale Audio with maybe a hundred hours on them. Also comes with the original Audio Research tubes, but I do not know how many hours they have on them. Enough has been written about this amp that I don't need to go on about how good it is. Positive reviews abound on the net.
Purchased several months ago from a fellow Audiogon member. Selling only to to upgrade to the 75SE...I hope it's better as the REF75 is really a wonderful amplifier in it's own right.
