The guru on fuses:

For two years, I have asked why and how fuses could possibly matter. All I got was arguments of faith, pro or con. I needed a real audio guru who actually knows. Here is a link from John Curl’s discussion on Parasound’s website. He engineered and designed some some great equipment, including some Mark Levinson gear, The Grateful Dead’s 30 plus McIntosh amp powered Wall of Sound, and his admittedly, somewhat price compromised Parasound designs. He discusses the electrical properties of standard fuses, showing how they are compromised. The entire article is quite enlightening, but to skip to the fuse section, go to the bottom half of page 6. https://www.parasound.com/pdfs/JCinterview.pdf

BTW, the John Curl interview you posted in your first post, if you comprehend it, only compares fuses as a "protection device" to save his amps from going up, nothing at all about comparing the ’sound quality" of them, I would stop insinuating John Curl is backing up your own beliefs.
I guess they speak a different kind of English down under. Or maybe it’s the comprehension part that is different.

The whole piece is on distortion and it’s effects on sound.

Curl starts out on protection devices and then goes on to the matter of fuses. On how they fluctuate current and that it hasn’t been measured properly. On how they vary resistance and how much that distorts.

If the piece is about distortion and its effect on sound, why would he mention fuses?
It wasn't mentioned as an aside.


All the best,

See this is where your (sorry Jethro) thick as a brick, and ( Sitting on a park bench)
There is no mention of sound quality because of fuses, it’s all as amplifier fuse protection parameters measurements.
You can have distortion measurements in countless other things than just in audio, allnoise.

So it is the comprehension part that is different, down under. 
Or it's too much of that Vegemite moonshine, again.

All the best,

Yes George a spring acting as a resonant whip..sh-t starts at the entry point of the device or circuit. You can spend thousands after that whiplash. Much better to avoid that tightrope before you pollute the whole circuit. I dont use fuses..
