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.

Turboglo and Vhiner, most reviewers don't have the benefit of manufacturers coming to their listening room and setting up already brokenin equipment and setting the room to optimize their equipment. And, of course, those who get this benefit may be listening to "special" pieces.

I just notified a manufacturer that I know the very special Urushi caps he and others use, take hundreds of hours to break in and that I would probably need a month and a half's access to his component.

I am also now using exceptional interconnects and speaker wires that may take 1000 hours of use to reach their best and may take two days to recover from being moved from one component to another. How I would love a piece that sounded exactly the same at 15 minutes and two years.
slow-blow vs fast-blo?

We all know fuses do make a difference (at least those commenting here). And I presume most of us -when we say fuse upgrade- are buying slow-blo.

But what if its fast-blo fuses that are best? Putting aside what the manual says, has anyone compared both types of the same value and brand?

No doubt some boutique fuse manufacturers are just supplying the same product for both fast and slow, but that's another story.
"No doubt some boutique fuse manufacturers are just supplying the same product for both fast and slow, but that's another story." On what are you basing that assumption? One might replace a fast blow fuse, with a time delay type, BUT- it would be VERY foolish, to do the opposite. ie: Generally; time delay is necessary, to allow a power supply's caps to charge. Rail or B+ fuses need to respond immediately, should a downstream device short/draw high current, or serious damage can occur elsewhere in the unit's circuitry.
MY BAD; I meant to say, "One might replace a Slo-Blo fuse with a fast blow type...." Sure would be nice, if this, "IMPROVED" site, still allowed for editting a post.
Simply put, replacing a slow blow with a fast blow risks "nuisance" (unnecessary) blows, while replacing a fast blow with a slow blow risks extensive damage to the equipment (and conceivably even the possibility of a fire) if a fault were to occur.

A substantial change in the "nominal melting" (amps squared-seconds) parameter of a fuse, which would result from a change between fast and slow blow types, amounts to a design change in the equipment, which should not be done without careful analysis. And the information about the design that would be necessary to do that analysis will generally be unavailable to the end user.
