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  I replaced the pre amp with a newer version of the pre amp and it has the same fuse value.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.

I never got suckered into that fuse crap.

I don’t have problems blowing any fuses, much less $50+ boutique fuses.

Only fuse to go to heaven was a HiFi Tuning silver, after pulling it out to clean the contacts, most likely my fault as the fit was rather tight, twisting does not work. Replaced it with a Furutech one, all fine and better.

Fuses do not impact audio quality. 
I’ve never blown a fuse in my audio equipment.

Several have commented on the "sound improvement" fuses can make.  Regardless of that point, if a manufacture cannot provide product stability in this case of a fuse used at the amperage recommended by the hardware manufacture why use it?

Good point J.Chip. The problem is none of them are better than the one they replace. They may look cooler but in many instance if not most, they are worse than the ones they replace.
