Audiophile Fuses


I have used audiophile fuses for years in various equipment without problem, generally appreciative of sound quality improvement. Recently, I've encountered problems with audiophile fuses blowing in my Coincident Turbo 845SE amplifier. At this point I've had two failures of Synergistic Red Quantum 6.3a 250v sloblo fuses in this amp.

Recently I discovered some interesting information in regard to audiophile fuses at partsconnexion.com website. In the heading above stocked fuses it states, "blow characteristics will differ slightly (due to the different metalurgy of the fuse elements) between commercial grade and audio grade fuses. We can't guarantee that your audiophile grade fuse won't blowout at different in-rush current thresholds than your stock commercial fuse."

They also mention one should check for continuity on fuse prior to installation to insure it will be covered by warranty.

And so, based on my experience, and quoting this message, it seems buyer beware on these fuses. First off, I doubt measuring continuity prior to installation will validate any warranty. How would dealer/manufacturer know whether or not you had installed a blown/defective fuse? Also, it would appear this request to check continuity prior to installation may demonstrate quality control problems as well. Do they not check continuity at the manufacturer and/or dealer? Or are they often damaged in shipment? If so, that is a high level of fragility.

At this point, I would advise caution in using audiophile fuses in high current amplifiers. The disclaimers stated on partsconnexion website demonstrate they've encountered this problem more than a few times. I applaud partsconnexion for they're forthrightness on this issue. Other manufactures/dealers should follow suit.

You may want to read what Roger Modjeski (Music Reference) found when he opened some of the Hi-Fi Tuning fuses. He posted his findings on the Music Reference AudioCircle Forum.
Your hero got booted off AC forum a while ago.

I've been using after market fuses for years and never had one blown. SR Red, HiFi-Tuning Supreme, Audio Magic ... Just make sure you buy the right size and type.
I think you should check your line voltage and make sure it is 121 V or less. The Turbo is prone to blowing stock 6A fuses if the line voltage is too high. Israel suggests a Variac voltage regulator set to 115 V. He is also OK with a 7A fuse. I would try the 7A fuse first.
so audiophile fuses not precisely measured to the blow current? did you try conventional ones?
I have also used audiophile fuses for many years, around twenty or whenever IsoClean fuses first came out. I also have had the Audio Magic Super fuse that contains liquid. All without any issues. I am also apparently one of the few folks who has actually revised the direction of ordinary bog standard fuses to get better sound. Why it's almost like the industry is stuck in first gear.
