Which SR Blue or black Fuse

I have to agree with geo, my input is what the amp was put together with, quality wire and the best electronics? That would mean a quality fuse holder too?

With that said most fuses that come with most gear are cheap, would a better fuse improve the unit? Anything better than what the fuse holder is made of, the units wiring and modules, might just be overkill? A better made fuse to match what it connects to? I upgraded mine, ye, but with the fuses that were one grade above the internals and holder.

Old school here. I’m sure there are a lot of technology I’m unaware of, but common sense, a drop of gold as a fuse make it sound better? Like what geo pointed out, same quality wire soldered in, step farther would be get rid of the fuse holder too...heheh

Thanks @geoffkait  @mental 

Fuses, fuse holders and the additional wiring ( or circuit board traces ), impair the sq, but, for the protection of the piece of equipment, it is there. One comment I always appreciated was by Bill Lowe of AQ.    " To Due Less Harm ". Better fuses ! Enjoy! MrD.

Remove all the screws from your gear, and replace them with titanium versions. Your gear will sound that same, but it will be slightly lighter, possibly resulting in the .0000023% sonic improvement attributed to fuse direction. I did say "possibly" but sonic enhancement from a fuse is mythological at best, and expensive at worst.

But what if you already have a screw loose?
