Dazzdax, Your question sent me down memory lane. 1972-74 and sitting in the barracks in Furth, Germany drinking "Rad" beer and rocking out on the Who, Golden Earring, Black Sabbath, Curtis Mayfield (and suffering thru the Chilites and the Jackson 5). Sitting in on weekend long hands of Spades, the music never stopped and the guys that had the 901's were top of the heap. My setup were 501's driven by a Pioneer SX 9000 with a Gerrard Zero 100 turntable, and an Akai R to R. 19 years old and Life was good. Dave
