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.

Hifitime , my Bose 901's has never sounded better after putting two coats of Elmer's Carpenter's Wood Glue on the paper cones and dust covers !!....

The purpose in doing this is to tame breakup resonance modes. In doing these coatings on these paper cones, you are able to extend the frequency range on both ends and avoid ugly response peaks in the midrange of these paper cones.

In all the years that Bose has been selling these 901's I'm amazed that they have not tried using treated paper cones !!...

I got more HiFi Tuning Supreme fuses in. The only one I have installed so far went into a prototype dac where I had an IsoClean fuse that had been Tesla coil treated by SR and painted by me with AVM. The result is typical. The sound stage became more realistic and the transients sharper. The other two will go into one of my preamps and into my phono stage.

Hi Wolf - I tried them forwards, sdrawkcab, miɿɿoɿɘb, uʍop ǝpısdn, and ndsıpǝ poʍu ɐup qɐɔʞʍɐɹps.

Hi Al - I agree it would be interesting to test a number of different cheap fuses. If my listening tests are valid, then there is an audible difference among at least some fuses. But like cables, more expensive doesn't always mean better.

Nothing beats a "realistic" soundstage. However, if my soundstage became more realistic my agoraphobia (not to be confused with "angoraphobia", an irrational fear of certain sweaters) would set in, and nobody wants that. To test fuses, I think you need 2 absolutely identical systems, or at least 2 identical pieces of gear with and without the "special" fuses. Then have somebody switch them without you knowing and allow for break-in time, perhaps allowing time for a visit to your therapist to help you with the compulsive side of your hobby/fetish ...there ya go!

In MF Shunyata Triton review, Caelin Gabriel invented the DTCD Analyzer that can measure anything that conducts current. He found even fuses measure differently. So theoretically fuses should sound differently in a component but like everything else, it's a function of the component.

In the PS Audio PerfectWave DAC II upgrade, fuses are one of changes. If all fuses sound the same, why bother changing the fuses? I'll let y'all draw your own conclusions.
