Krell fpb 600 svs ultra tower

Also sorry for saying it trips the Krell 20 amp breaker. I meant to say the 20 amp household breaker in the panel dedicated broker Then to run 10 gauge with 30 amp like Kell recommends 

I had a Krell FPB600 for ten years. Best sound with balanced cable to the preamp. I liked it best with a tube preamp (Aesthetix Io with volume). There is some protection circuit/jumper to protect against preamp misbehavior, I removed them, got better sound, and never had a problem. The one problem I did have, was that it sounded best at a volume level that was too loud for me (more pure class A at higher volume). But it is a great amp, and in some ways I miss it. Far better than two Krell KAV line amps I had, before the 600.

And yes, the FPB600 loved a dedicated line, it got even more authoritative, deep and precise. In my 15 ampere line it never triggered the fuse - but that is in Europe, at 220-230 volts.
