harmon kardon 730 vs concept 16.5 and pioneer sx1980

[Guest denmarkdrivers]

Hi i own a harmon kardon 730 twin powered reciever, i tested it against a lot of equipment but i stupidly passed on a couple of resale steals, concept 16.5 for 45 bucks and a pioneer sx 1980 65 bucks. Anyway i now know i should not have passed on them, i'm curious are they sonically better then the HK 730 twin powered reciever ? i already tested it against marantz and some other models i liked the hk more but i never got a chance to hear a concept 16.5 or pioneers big power recivers from same era, would the harmon kardon 730 twin powered sonically beat them ?
