Around 1986-7 at an audio store that sold some nice stuff Denon, Bang&Olufsen,Klipshorns,Nakamichi etc.I overheard a salesman call the PA5 and PA7 amps wimpy.I never had one and I dont know why he said that.I too always heard the designs from Pass were good into very low impedances.Just another story,doesnt mean much,YMMV,Bob
