Is there a solid fuse-like item that I can use in place of a fuse, to bypass it?

Hint a non UL approved device with dual polarities available in diiferent shapes including rods and cylinders and in different strengths. Enter at your own risk.

One reason all fuses sound different.

Electro mechanical fields are always in motion so they always generate resonance and vibration that attaches  interfering energy upon the originally  intended signal. Tom

Yes thats why their fuses sound inferior..They don't know or care to know why their products sound bad because they couldnt conceive that there wire trapped in a tube would matter to the sound or performance of its host.

The fuse is the entry point for electrical noise to enter and to have shear wave energy  generated and regenerated inside a glass pulsating distortion capsule. This interfering shear wave energy goes onto influence every signal in the chain and beyond.

Open your  brain.

Anything that moves generates shear.

Your speakers and  all materials and surfaces even the fuse..

A polarity of shear left to regenerate will keep reproducing shear especially in a glass tube.Tom

Your speakers drivers are flexy and they operate on shear an compression.

Shear travels from the moving coil and dust cap and both sides of the cone and a polarity of this shear wave is reflected back down the cone corrupting the next wave launch. A fuse contains an element that vibrates with electricity, you can see it in the video posted before it blew..that vibration is never totally mitigated. Transformers vibrate so they will also generate shear and pass it down the line. And so it travels.Tom

Shear is a component of all vibrating surfaces.. Speakers, walls, violins  cellos their strings and bow vibrate and generate shear just like a fuse vibrates when its host is turned on and running. Tom
