We Need A Separate Forum for Fuses

Looks like Almarg sums up the point eloquently

But it was, in the end, an assumption. Most engineers would consider a fuse to be nothing more than a protection device, since that's it's intended purpose. It turns out though, that it has ramifications beyond it's intended purpose, and there are those who've bothered to see for themselves if there's any benefit to changing the fuse for a better one, as  opposed to those who simply refuse to try.

All we're doing here is going in circles.

Nonoise, it sounds like an excellent marketing ploy.

Then let's put the assumption to the test. I will make my build of the F5 available to anyone within reasonable driving distance of Toledo, Ohio with a scope, signal generator, and distortion analyzer.. This is an amp with a 600VA toroidal, 120,000uF of filter capacitance, and 32V rails. It will reliable drive 30 watts DC into a 2 ohm load and peters out on the top end around 1,000,000Hz. I think that should be sufficient to measure any audible artifacts contributed by a fuse. Please message me to make arrangements.

Kosst,
I'm way the hell on the other side of this continent. Just do yourself a favor, try a fuse and trust your own ears to see for yourself. You don't need anyone else, unless you don't trust your own hearing. 

All the best,

I'll pass and I'll tell you why. The power supply in that thing is big enough to be immune to me sitting there rapidly flipping the power switch on and off. The LED indicators all over it don't even flicker. Second, I do doubt my hearing at higher volume, which is where I'd expect a discernable difference.
