Hi Fi Tuning Supreme fuse-Burn In?

From what HiFi Tuning says there is actually nothing about the construction of their fuses that could lead to any sort of bad outcome. Fuses are not really rocket science. You simply choose the wire for a given fuse based on whatever temperature you want the element to melt. It’s not complicated. On the other hand, there are certainly reasons not related to the fuse construction that could explain why fuses blow prematurely or whatever. E.g., operator error or the recommended amplifier fuse value was underestimated by the amp manufacturer. By the way, if the vibration damping tube in HiFi Tuning Fuses was actually a problem I’m pretty sure HiFi Tuning would have eliminated it by now. That’s just common sense. As I already mentioned, sand-filled fuses would constrain the plasma as much as a tube damper. Plus there are no issues will sand-filled fuses or liquid filled fuses or beeswax filled fuses, for that matter.

“HiFi Tuning has long been a fan of Germany’s legendary Mundorf capacitors. Revered in audiophile circles for creating gorgeous sounding no-compromise capacitors which grace some of the world’s best electronic designs, Mundorf capacitors are built using a special conductive material. Ultra-pure silver is impregnated with gold creating a material with gobs of resolution and golden warmth; glorious tonal color with truly outstanding dynamic shading, essentially the best of both gold and silver and absolutely no compromise. Each Supreme fuse uses this special material for its end-caps and conductive filament and pure silver solder connects everything. Inside the ceramic casing, Supreme fuses further distinguish themselves by receiving proprietary resonance and quantum treatments.”

@ramtubes: I thought I was pretty concise, when I stated, " I’ve had HI-FI Tuning’s fuses(Gold and now Supremes) in my Cary monoblocks’ mains and B+ circuits, for over 12 years, without a problem. That’s not counting when the occasional tube took a crap and the fuse did it’s job." My amp’s manual calls for a 3A slo-blo and a 500mA fast-blow(B+), YES- both specified 250V, which is what I’ve been installing. Do you just assume everyone you address is as incompetent, as your customer that blew up that ONE prized example?

I COULD also mention: when I auditioned a pair of Claus Bunge’s excellent Odyssey monoblocks, in my home, a few years back, I had occasion(with his permission) to remove the top cover of one. In the rail voltage(DC) fuse positions, lo and behold, were four HI-FI Tuning Golds. He’s apparently had the same success as I, with HI-FI Tuning fuses, in my modded Trans-Nova 9505, woofer amp’s output stage, rail voltage(DC) supplies.

It seems, quite a few that frequent this site, value the opinions of the Stereophile Magazine writers. Personally, I would think, they’d be somewhat conscientious, as much as they value testing things, before recommending a product/tweak, in their reviews and follow-ups. ie: https://www.stereophile.com/content/hifi-tuning-fuses and https://www.stereophile.com/content/hifi-tuning-fuse-follow-may-2012 It appears, no one(as of 2012) told them, about all those amps being destroyed. I’d further have to think, that highly experienced sellers(ie: Music Direct, VH Audio, Parts Connexion, The Cable Company, etc), would have been made aware(by now), were there an issue, and avoided selling anyone's, "high-end" fuses(and any possible, attendant liabilities). There again: Just my own observations/opinions.
