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!

Littelfuse spec 5A 250v Slo-Blo 21.4mΩ
Measured 22mΩ with precision supply and resistor divider @ ≈115mA

Measured R after 10 minutes at each current.
0.55A 31mΩ
1.10A 31mΩ
2.20A 31mΩ

Power Transformer input Z ≈100Ω. Fuse is 0.023% of input Z.

Please explain how ZERO change in fuse characteristics can rob low level detail.

Crappy holders in harsh environments can create ugly artifacts. Ditto poor quality or wrong characteristic holders or fuses.
👍

This says it all, "if" you voodooist fusers can understand

Good work for the effort measuring


And if you want to change your old crusty fuses that may have seen too many turn on cycles (pics attached), then do it with the same $1 fuse, not the BS $150 SR boutique ones, as they will sound the same and age just as fast.

Pics of fast and slow blo fuses that have seen too many turn on cycles over a couple of years.

Frank please don’t use the words science or scientific as some people might get very upset. School, as a kid, my mother would say, “You should enjoy it. One day you’ll have to work for a living.” No, I won’t, ma. I’m going to me a comedian. 🤡

roberttcan,
Do you work for Thermotron? That is a great company & one I'm very familiar with (I live in the area). We had one of their chambers in our R&D facility for years. It served us well.

Speaking of thermal chambers, a friend of mine who worked at Wright Patt AFB in Dayton, Ohio volunteered to see how long he could make it in a thermal chamber at 400 deg. F. He was in street clothes in the chamber for 25 minutes, no big deal. I worked at W-P in a pink building with no windows.

...but it did have padded walls.
