I recently pulled our my Harmon Kardon 730 twin powered receiver to use in office. I bought this along with the Original large Advent speakers in 1978. I used it up until the late 90's. When I first turned it on and heard the full sound of this amp, I remembered why my wife & I had liked it so much. I was going to sell it but I may get it restored instead. Though a receiver, this thing can hang with separates & surpass some without a doubt.
