I'm not sure what the 15amp circuit will do to the sound quality but I have run plenty of construction machinery over 15amp circuits and they trip the breakers constantly. If we run it on a 20amp circuit we do not experience the problem. If you run the Krell on 15amps and someone turns on a microwave or hairdryer or a coffee maker, that's on the same circuit as the receptacle the Krell is on, you may be making trips to the breaker box
Can you put a Krell in an apartment?
As you see I am a total "goner" living in a cheap apartment with about 50 grand in Audiophile equipment. I am looking at purchasing an old krell "FPB 400 CX" amp that the manufacturer says needs a dedicated 20 amp line. Can you still run this amp off a regular electrical outlet? If you can, will it sound like crap?
