To Fuse or Not to Fuse... That is the question!

Ok.. I think I understand that no fuse is better than a cheap fuse. And a good fuse is better than a cheap fuse. But is no fuse better than the best fuse?

One person on Audiogon said that he achieved better sound by using a Blue fuse over no fuse. I guess my question is... Do these new, high dollar fuses just allow the current to flow better with solid protection or do they actually due to quantum physics or something, actually improve upon the signal by eliminating errant bad electrons and thereby actually improving the music over no fuse at all?

I gots to know!

Why? Because you are starting to realize that you can't just throw up some terms in hopes of baffling me with BS?  ...

Energy passes through that fuse in both directions ... it has to. The voltage potential reverses direction and the EM field must change direction as well. Electrons move in the fuse in both directions, and the EM field in bulk will be the same. Add in that most power supplies are symmetric for both polarities of the AC line. Energy is (line feedback excepted) transferred only from the AC source to the equipment but sometimes it enters through the fuse, and sometimes, the fuse provides the exit path. Either way, it is always there, and always has an impact no matter the polarity of the AC. It is always acting as an element in the circuit, in both directions, and equally.

@roberttcan, I take it therefore that fuse "directionality" is, you would argue, impossible?

Since you ask you have shown you don’t know the difference between a field and a wave. Or between an electron and a photon. And you’re unwilling to learn. You are a classic pseudo skeptic on a mission.  For those reasons I’m out. See you in the funny papers.

Theoretically, as I noted, transmission line effects are possible, but would be at such high frequencies as to have no possible audible effects. 

Far far more likely, would be simple, and practical effects, not geoffkaits physics babble.

Fuses and fuse holders are mechanical devices. It is possible that the combination of the fuse shape and the holder shape is more conducive to lower resistance in one direction. However, don't get caught up in the trap for AC fuses that less resistance is always better.

Ditto, fuses are thermal devices, a better mechanical connection in one direction coupled with a fuse defect resulting in asymmetrical heating could cause more thermal modulation in one direction. However, unless the fuse is pushed to its limits and the amplifier has some serious serious design issues, thermal modulation of the AC fuse is not going to be audible.
