Upgrading Fuses


Have a Audio Research Ref 3 and am considering upgrading the fuses but I am a little skeptical. Would like to hear from people who have try this. Hard to believe that fuses can make a substantial difference like the manufacturers claim. All advice appreciated.

"Not all amps have fuses...Krell for example."

That's crazy talk. Must have a fuse, no? I've never heard of such a thing. For nothing else so that your house doesn't burn down.
Krell amps use no fuses. I believe so they don't impact the sound quality.
I'll just wait for a knowledgable Krell owner with experience to post on this question. I know someone who owns four of them and he says they have no fuses. Until then I'm sure there'll be a week-long theoretical debate about it.
Of course Krell uses fuses. Go to their website and download the manuals like I did and read about the fuse specs like I did.
