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.

I have found that the Synergistic Red fuses blow to easily. You may have to go up in value.
How do you the fuse isn't just doing its job? Maybe there's a problem elsewhere.
Sns,
Have you experienced this problem with other brands of fuses?
I have the Coincident Frankenstein MK II, their Statement Line Stage and the Yamamoto YDA 01 DAC. I've used the Synergistic Research Quantum fuse in these components the past 3 years without any problem. I've found these fuses to be very worthwhile and cost effective given the increase in sound quality that they provide.

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.
