Fuses that matter.


I have tried six different fuses, including some that were claimed to not be directional. I have long used the IsoClean fuses as the best I have heard. No longer! I just got two 10 amp slow-blows WiFi Tuning Supreme fuses that really cost too much but do make a major difference in my sound. I still don't understand how a fuse or its direction can alter sound reproduction for the better, but they do and the Supreme is indeed! I hear more detail in the recordings giving me a more holographic image. I also hear more of the top and bottom ends. If only you could buy them for a couple of bucks each.

It should be possible to determine that by unplugging the amp, removing the fuse, and checking for the presence or absence of continuity between the AC hot pin on the power plug and the contact at the accessible end of the fuseholder.

Ahh, of course. Don't know why that didn't occur to me. Thanks, Al.

Do you "re-fuse?" (my 32nd most cerebral pun of the decade). Follow the rubber line. Now I feel I have to take every piece of my gear apart and see if the wires are "direction appropriate"...would an electron microscope be useful in detecting the optimal wire grain orientation direction? Damn...this is gonna take forever....
Wolf_garcia, Forever? What about house wiring. You have no idea how long and painful it was to pull and reinsert wires in opposite direction. I'm working on power company to do the same but for some reason they are very resistant to this idea (definitely not audiophiles)
Although I now own them, I don't take fancy fuses very seriously. I bought them largely out of curiosity, after reading dozens of testimonials from audiophiles who reported hearing results. I too thought I heard results. I'm happy to be wrong about that. I don't mind being the victim of placebo, and I don't feel the impulse to defend my initial listening impressions. Listening impressions, and particularly the inferences derived from them, can be mistaken for all kinds of reasons.

Having said that, I tend to take audiophiles' listening impressions at face value, unless I have a good reason not to. Sometimes I have a good reason. But most of the time, I recognize that he was there in the room and I wasn't, so why not give him the benefit of the doubt that he heard what he heard. The benefit of the doubt can always be withdrawn, and very little is lost except some conversation. All of this is prologue to what I'd really like to say, which is an observation followed by a question. The observation is this...

It's widely (though not universally) acknowledged by people who are both audiophiles and experts in electronic design that, in addition to the Known Parameters that affect sound quality, it is likely that there are Unknown Parameters that affect sound quality. Those Unknown Parameters are either unmeasured or unmeasurable, though that could change with the progress of knowledge, either theoretical or applied.

And the question is this...

For those who acknowledge the likelihood of Unknown Parameters, what is the standard by which Possible Unknown Parameters are distinguished from Impossible Unknown Parameters? Since by definition it cannot be the standard of prevailing knowledge, it must be something else. But what? Intuition?

If the answer is intuition, I can accept that. I believe intuition is worth something. In fact, I believe it's worth quite a bit. But I will point out that intuition, even the intuition of experts, has been wrong innumerable times, with consequences ranging from trivial to amusing to catastrophic. In fact, there is reason to believe that intuition is wrong far more often than it is right, for the reason that there are VASTLY more ways of being wrong than being right.

So again, what is the standard by which Possible Unknown Parameters are distinguished from Impossible Unknown Parameters? I ask this because, IMHO, the idea that wires are directional or that fuses can affect sound quality, while they may be outside the scope of prevailing knowledge, fall within the scope of possible knowledge.

I could be wrong. People usually are.
