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

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..

OP, someone gave me a hand full of SR fuses and ask me if I would like to try them. I have NO skin in this game...

I was using ACME and Tuners. I tried a SR in a hot rodded Samra C20. There was a nice change. It took 50-100 hours to sound its best, but the change was instant, it just got better.. a Blue SR.

I just have the fuses in a few pieces of equipment, and in some equipment they sound really good. Others, no change at all. 

I'm not quick to say, it changed either.. It had better change, or I will tell you.. You're hearing nothing BUT.... I have a friend or two.. That can talk themselves into or out of anything... lucky for me...  
They go sideways, more so, because they can. 10-30k every year for the last 15 years.  its just money to them.. ME I'm pretty frugal.. NO 150.00 fuses that I paid for... 10-25.00 usd..

The fuse he was talking about was in the speaker circuit, not the power circuit.  Also note his comment before about building an amp that he thought he did everything right, but still blew up when shorted. Just because someone has a "fancy name" even John Curl or Nelson Pass, they can be wrong and there are limits on their knowledge.

I would like to recommend you purchase Littelfuse fuses, which cost $4-8 each,  before getting $100 fuses to try. Yes!  they make a difference if your system is transparent. Don’t listen to others who say it doesn’t make any difference. The same people say Cables don’t make a difference.
