New Synergistic Master Fuse

No fuse at all would be a solid wire/jumper.

Or a magnet treated  with 1 additional process and 1 surface enhancement. Tom

The Master Fuse,  One fuse to rule them all.

An audiophool and his/her money is soon parted!

I suspect that all similarly rated fuses sound the same, but when you replace them, the contacts are remade and that's why they sound better.

But - and it's a big but - a lower impedance fuse will sound better than a higher impedance fuse, and impedance is correlated with the current (ampere) rating.
