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.

How do you the fuse isn't just doing its job? Maybe there's a problem elsewhere.

Why is it that when a regular fuse blows, people are concerned about their gear being damaged, but when an audiophile fuse blows, something is wrong with the fuse itself?

"If this power cord sounded better on your preamp would you feel safe using it?"

Yes, I would feel safe using it because I didn't fool with the fuses in my preamp.

What if the audiophile fuses made the sound worse? Would it still be a placebo, or would the negativity legitimize the results?

"A fuse should not change the sound .So yes if you hear a difference either way ,yes it is a Placebo. If someone hears a difference that's fine with me.A fuse is a fuse is a fuse!

You're loosing me here. I consider myself to be more on the subjective side when it comes to audio, but I still consider objective factors, and try to find a balance. Your answers, at least on this topic, are purely subjective. And that's OK. You're allowed to think anything you want. But if you are presenting a different view, I'll need to see at least some factual info, in order for me to agree with you.

Zd542, Have you ever done a blind listening test with your fuses? Just like the difference with gold and silver plated spades on speaker cable,. I think you will come to the conclusion that it is all just Smoke and Mirrors! But like I said,if you hear an improvement that's great!"

You completely missed my point. You're referencing things like placebo and blind testing. That's fine, but in order for those terms to have meaning, they need to be used properly. And the only way that happens is if you conduct a test and get some type of results. You haven't done that. You're guessing. You assume the placebo effect is in play here, and you're guessing what the outcome of a double blind test will be. You also seem to be getting frustrated with me because I'm not taking your guesses at face value. For that, I make no apologies.

You haven't done so either. And remember, these are your claims, not mine.

If you like, conduct whatever test you feel appropriate to compare the sound differences between fuses, and post the results, along with your testing method. Then I'll go buy the same fuses and try the same test myself.

I can't figure out what you are talking about. You keep changing.

"The only test is in the listening."

You said that if you hear a difference its just the placebo effect.

"How do you know that I have not done listening with different brand fuses?"

I don't.

"A fuse at the same rated value will measure the same."

What are we measuring? This is a new topic.

"I just do not understand what the problem is ? Have you used fuses and found a difference?"

Well, as long as I have the same opinion as you, there is no problem. You won't allow for anything else.

Jea48,

Thanks. I always wanted to know how to do that. Normally, I would do something like this if I wanted to quote you.

"Web addresses must start with http."

Is this right?

[Web addresses must start with http.] And I would now type my reply as I'm doing here.

If the above is right, I get the part about shrinking it. Thanks again.
