Something For The Fuse Guys ...

Yea well the problem is Op offered to send me a fuse to try and I accepted because I was genuinely curious. When I reported back and did not get the advertised results I was marginalized and my ability to listen questioned.  One particular "pest" suggested my findings were an outlier and should be disregarded. Not preaching the mandated fuse product gospel did not go over well with anyone.

Good news is I know from experience just the act of reseating a fuse can make a difference so changing one surely can as well. Of course nobody ever factors that in rather any positive change reported is automatically attributed to the fuse. I may have even heard some difference with the fuse sent but if so it was very minor and hard to confirm. I ended up going back to the stock fuse in my Arc pre-amp which appears to be of very good quality.

To me its like wires and power cords. They can make a difference but not always. Some are just designed way differently than others and some are cheaply made and some not. Maybe replacing a cheap or partially blown fuse with a new or higher quality one can make a big difference in some cases. Most likely when directly in the audio signal path like with Magnepan speakers but that is usually not the case with most home audio electronics.

So that’s the story. mapman out.

I did a fairly extensive test of the efficacy of SR fuses a while back...recorded results to play for reference, tried reversing them, had one blow for no apparent reason, and otherwise tried hard to see if the things made any difference...they don’t, and another interesting thing about the endless nonsense regarding Magic (and expensive) Fuses is nobody has offered up any reasonable explanation why they would. 

Whoa! What the ding ding?! Folks, can you believe it? we have a tie!! Pseudo skeptics 4, fuse apostles 4. We even have wolfman and madman repeating their same dreary claims of “extensive testing” and that nobody has explained how fancy fuses work. Yawn! I’m feeling a little sleepy. Now, get back in there guys and let’s see the feathers fly.

Mapman sez people can draw their own conclusions. Oh, you mean like the 100,000 happy campers who have bought audiophile fuses? Good detective work, Moops! 

It is simple to test if your fuses are limiting something without having to invest hundreds of dollars.    Just jump them with some spare wire and have a listen.  You can even get fancy and jump them with pure silver solid or other exotic wires.    If you can't here any difference it is unlikely a fancier and expensive fuse will work.
You can decide if you want to live on the edge and skip the fuses.   I never blew an internal one in anything solid state.
