The guru on fuses:

For two years, I have asked why and how fuses could possibly matter. All I got was arguments of faith, pro or con. I needed a real audio guru who actually knows. Here is a link from John Curl’s discussion on Parasound’s website. He engineered and designed some some great equipment, including some Mark Levinson gear, The Grateful Dead’s 30 plus McIntosh amp powered Wall of Sound, and his admittedly, somewhat price compromised Parasound designs. He discusses the electrical properties of standard fuses, showing how they are compromised. The entire article is quite enlightening, but to skip to the fuse section, go to the bottom half of page 6. https://www.parasound.com/pdfs/JCinterview.pdf

When they build an amp. or pre amp or what ever, aren’t better components, BETTER?. Look at the copper foil resistors, I thought WIMA caps were the reason for the great but reasonable cost of HIGH quality sound... It’s not, it the resistors.. AND they do make a huge difference in SQ..

SO WHY are you so resistant to a damn fuse... Beyond me.. I don’t get it..

Every time I use this fuel my car does this.. OK, do you like what it does?
NO, pings like a pong! Sounds like it’s gonna blow up... Answer. don’t use that fuel. BUT I use this other fuel and it runs even better, same octane. What do I do.. REALLY? oh by all means use the crap fuel...

I dunno... maybe I’m just too emotional.. about the whole thing...LOL
Go hug my speakers... They know they get the best...

I had my ARC Sp10 fail in 1989 when it caught on fire before the fuse blew I was able to unplug it..

Why oldhvy because for all the bs about an amp just modulating the power supply, the reality is what makes for a stable supply and the properties assigned to audiophile fuses are not the same. It's all a smoke screen of ignorance.  Fuses feed into 10s or more feet of wire in a transformer and high inductance. Conveniently forgotten. A fuse that increases in resistance as it heats up (more current) would make for a more stable supply voltage. Yet people go gaga over low resistance. That is what happens when people who don't understand amps and power supplies make conclusions based on suggestion.
