That guy from Psionic Audio is a dipshit who seems to ride the high horse with his opinions, while ripping people off constantly!!!!
Type "Ripped off by Psionic Audio" into any search engine, and you will see what I mean.
He had the balls to say he could improve TopHat amps. In his dreams. Brian Gerhard (Tophat) knows how to build amps period!
As for Boogie amps being unreliable, I have owned 4 Boogies and only had one problem in all 4 of them. Yes they stack
a bunch of stuff in thier amps, but most of these amps have ton of options so there's not going to be a bunch of room in the chassis.
There is a tech named Mike C in Salt Lake City that totally knows his way around Boogies, I had tube go bad in my Fillmore 50 but that
ain't the fault of Mesa. He had my amp back to me in less than a day.
As for Metropoulos Amps, they are stellar. The guy knows how to build a Marshall better than Marshall.
