Many, including myself, have questioned the hyperbole and silly claims of the efficacy of Magic (re: expensive) Fuses, and also question the claims of those who condescendingly imply that those who don’t hear the alleged benefits are inferior listeners. Having tested SR fuses against stock fuses myself, with the failure of a couple of the SRs noted (fuse rating issues are common with SRs, not so much with Littelfuse or Buss products), I found that indeed, the SR athletic supporter's claims were nonsense. I carefully recorded my system with my high res recording stuff to compare the SR products with the stock fuses, played the recordings for some friends, and none could hear improvement from the "boutique" fuses. People may feel better using pricey fuses and of course that’s to be expected, but all the proof I need regarding the alleged sonic transformation the things provide is my experience, applied logic (understanding what power supplies actually do being outside of the signal chain), and the fact that virtually no equipment manufacturers seem to care about using "special" fuses in the gear they design. If anybody took up oregonpapa on his offer, I can only assume he’d replace the SR fuses with stock versions for comparison to the SRs he advocates. That certainly would be interesting if not a bit fiddly...would break-in time be allocated? Snacks? A directionality seminar covering each fuse? Casa oregonpapa here we come!
So done with audiophile fuses
The journey started with a medium priced ($50) fuse in my power supply. A failed rectifier tube blew that one out. Not a fuse problem. Next up was a blue fuse in my pre amp. It blew and was not caused by a pre amp problem. Apparently they sometimes are more sensitive and it was replaced by an orange fuse two values higher. Things were going along fine. I replaced the pre amp with a newer version of the pre amp and it has the same fuse value. Five months latter (today) I turn on the pre amp and nothing. it's a five month old pre amp so I suspected that it was the fuse. Sure enough, I replaced it with a ceramic Littelfuse of the lower correct value it works fine. No more wasting my money on unstable fuses for me.
