I wish to settle a question posted on many forums...Who built this amp ??
I've seen Crown, ATI, Bryston and Proceed...Sorry, it was Marantz...The S650 was an upgraded 5 unit version of the Marantz MA500...If you doubt, just look at pictures of the interiors side by side...And Marantz is printed on the circuit boards !!
