Twl, your comments show gross rudeness. Your adolescent, condescending comments should be kept to the high school playground.
You assert that the elimination of the output transformer accounts for an amp that weighs 10 pounds. Transistor amps don't have output transformers, but they have heavy power supply transformers, just as tube amplifiers have, either with or without output transformers. Your comment regarding this shows gross ignorance.
As far as opinions comparing them to 20K amps, there are many opinions comparing X, Y or Z amp to a costly counterpart. Berning has no corner on the market for such praises.
