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 used to sell a lot of fuses at Radio Shack. I also replaced a lot of blown fuses in customer gear at Tech Hifi.

It's been a while since a fuse in an audio device and myself have crossed paths, but the concept of a directional fuse seems new to me. I do not recall anything dealing with one orientation versus the other? Of course, I may have dealt with a few audiophiles but most were normal people who just wanted sound to come out of both channels of their amps.

For the amp (Pass XA30.5), I can't tell whether the fuse is pointed downstream or not. The fuse is held into the chassis by a cylindrical fuse housing that screws into the rear panel. Anyone know if there's a typical orientation for those kinds of fuse holders?
Hi Bryon,

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.

Best,

Naysayers don't realize importance of the fuse and its influence on the sound. Just to test it I removed fuse once from my amplifier and sound was gone. I mean gone completely. Fuses are absolutely necessary for good sound.

Kijanki, so what your saying is that depending on the state of that little filament inside the fuse, sound quality can range from extreme paradise to nil...and anything in between?

Kijanki, I know what you mean. If I take all the gas out of my motorcycle it handles much better due to reduced weight but it doesn't accelerate very quickly. Also makes the $1000.00 Staintune exhaust seem like a waste of money.
