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.

"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.

Hopefully, people listen to AL in that that is really the thing that "matters" most with fuses.

How different ones in good operating condition sound is a distant second IMHO. Lots of other ways to tweak ones system without putting it at risk IMHO.

Mapman, I like the IMHO. As long as people respect the fast versus slow distinction and the amp value on the stock fuse, experimentation is perfectly safe. Why you would advocate avoiding the fuse tweak, I don't understand.
