my favorite was the 775 Mono amps IMO the best amp ever made by HK better than most of the citation series! One of the dumbest things I ever did was to sell them to my best friend (still going strong)
Older HK pre power 725+ 770 v 825+870
If one was looking into older HK which would be the better sounding pair to go for The 725pre and 770 power amp or the 825pre and 870 power amp. I know there is a power difference. The sound of this older HK gear seems to be very sweet and musical. Thanks,KG
