Fuses that matter.

(a)The EXPLANATIONS that are offered for their purported effects do not stand up under quantitative scrutiny.

Hi Al - There's a guy over on the Polk Audio forum who claimed his measurements corroborated both that fuses measure differently and that even fuse directions measure differently. You can see his measurements here. I don't really know what to make of it. What do you think?

(b)I suspect that a substantial number of reports of differences, but certainly not all such reports, are due either to failure to recognize and control extraneous variables, or to effects that are system dependent and do not have broad applicability to other systems, or to misperception.

This happend to me, as I described in an earlier post on this thread. When I first installed the Hifi Tuning fuse in my amp, there was a noticeable jump in headroom. I thought, "Wow, these really work." When I later A/B'd the Hifi Tuning fuse with the stock fuse, I could not reproduce the effect. Therefore, my initial impression was either (a) misperception or (b) attributable to some other variable (cleaner contacts, better grip on the fuse, etc.).

(c)I see no reason to expect that where a fuse upgrade makes a difference that the difference will always, or even usually, be for the better.

This also happened to me, as I mentioned earlier. After extended listening, I preferred the sound of the stock fuses to the Hifi Tuning fuses, both in my amp and my preamp.

Of course, I've since ordered fancy fuses from two other manufacturers -- Furutech and Isoclean. So maybe I'm in for a real treat! Hmm. For some reason I'm reminded of birth rates.

P.S. For a limited time only, I'm making available a pair of Hifi Tuning fuses. I've done the courtesy of breaking them in for you. Just $300 for the pair. Don't miss out!!

Geof, my new audiophile fuse will be called "The Funky Little Fuse". The design goal will be to deliver the soul of the music. If any music that does not have soul comes into play it will blow but be replaceable for a small fee.

Hope there is no copyright infringements here! The principle by which this fuse operates is proprietary intellectual property so I cannot discuss, although it will be quite amazing I am sure.

Cheers! :-)

geoffkait, I knew what Rogermod thought he had proved and was saying about microvibrations, but it was a good point to note that he had proven only what most knew about resistance and nothing more. These pseudo-scientists fail to disprove what observations tell them-there is a difference in fuses. Rather than a priori refusals they should get to work finding what accounts for the differences. I know they always suggest that is delusion to hear a difference, but refuse to listen.

Almarg, you said,

"Scientific investigation and scientific progress draw upon a combination of observation, experimentation, analysis, technical understanding, and (dare I say it) reasoned judgment and common sense, among other factors. I see no reason for audio to be any different."

I see many reasons why this is different for audio. One need look no further that the cable controversy, now more than 30 years old, with no resolution in sight. Amplifiers with the lowest THD always sound better than one with higher THD, even 10 times higher. I implore you, is that reasonable, does that make sense? Extremely thin cables can sound better than much thicker ones. Again, does that make sense? Mpingo discs - how can one small 1 1/2 inch ebony disc in the room completely change the sound? It doesn't make sense. Green pens for coloring CD? Doesn't make sense. Schumann frequency generators that improve the sound? That's patently absurd. Intelligent chip with quantum dots improves the sound of CDs? Ridiculous. A cream that improves the sound of CDs or LPs when applied to the surface of the disc. Now, don't tell me that makes sense. Quartz, topaz, tourmaline and other types of Crystals for everything from cables and power cord plugs to room corners and electronics. Is that reasonable?

Tiny little bowls that improve the sound, even bass frequencies. I implore you, does that make sense? I'm afraid what we have is a revolution in how we look at the hobby of audio. Of course, we could ignore it, but doesn't it make more sense, and isn't it more reasonable, to take advantage of these new technologies to improve our lot?

There is such a thing as "technical intuition". This is what enables one to assess technical facts and draw conclusions that have a godd chance of being accurate. Its a rare thing. Based on his posts, i would say almarg has it to an exceptional degree.

Machina dynamica? Not s much in my humble opinion. Sorry but thats what my "technical intuition" tells me. Just being honest.
