So done with audiophile fuses

Ahem. In what 3rd world country do you all live where shorting a fuse in an audio amp starts your hovel on fire? Move into the modern world, where our buildings have code, and our breaker boxes have, uhhh, breakers installed.
As for your insanely expensive amp, yeah, that's going to release its magic smoke, and be worthless, but you'll still have a shanty in which to keep it.

And, ummm, if your amp blows a fuse more than once, it's trying to tell you it doesn't feel so good inside. The engineers who designed it did lots of math to determine how much current the thing should draw, and how much is too much, then they put a fuse in there to burn up before your tubes, transistors, and worst of all, your transformers burn. For cripes sake, DO NOT short it out, or put anything else but what the engineers calculated! TAKE IT TO THE AMP DOCTOR!!! Putting a higher amperage fuse is saying, "Something's wrong with this machine, it's using more power than it can safely handle. Maybe if I feed it even MORE power, I'll never need to have it serviced," and you might end up being correct. And the engineers who built it will be sad, and the salesperson you buy it's replacement from will be stoked. And that's really what this game is about, right? Happy sales people.

Did anyone contact the aftermarket Fuse manufacturer and inform of faulty product?

Happy Listening!

What kind of disclaimer comes with the "audiophile" fuse supplier denying any subsequent damage caused by installing a fuse value that is higher than recommended by the audio component manufacturer. Will the manufacturer gladly replace the 50 cent fuse sold for $hundred$ that blew up a $100,000 Boulder amplifier? Yeah....

Will the manufacturer gladly replace the 50 cent fuse sold for $hundred$

Not if they're smart, they won't. They should have an official policy of not recommending anything other than the manufacturer's rated part, which is always clearly marked on the device. Even if I was selling 50 cent fuses for 75 cents, I'd have literature clearly stating that using the wrong value voids any warranty. Maybe I'd send you a  coupon, two fuses for only $1.65, and better looking, I mean, better luck next time, kid.
