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.

I replaced the Gold Hi Fi tuning fuses with the Supreme tuning fuses in four components with excellent results. The gold made nearly no difference but the supreme was clearly a step up.
Here are the putative explanations I've been able to find for why a fancy fuse might improve sound quality...

1. Lower DC resistance
2. Less voltage drop
3. Lower microphonics
4. More conductive materials
5. Better electrical contact between fuse caps and fuse wire
6. Better mechanical contact between fuse and clips
7. Better conductivity due to cryo treatment

For the folks who know about these things, do any of those seem plausible?

Bryon, If these fuses make "major difference in sound" as Tbg stated then why manufacturer's don't install them in gear they sell - they do install many other expensive parts. Perhaps they feel that the difference in not so "major" (if any) and not worth price increase (even when amp costs $50k). Do you know of any manufacturer, even very pricey one, that installs "supreme" fuses in stock gear?
Kijanki, manufacturers don't want to alienate other fuse manufacturers or prospective customers as they don't want to alienate cable manufacturers or customers. I know several manufacturers who privately express opinion on fuses.
