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 cannot speak to any of the technical aspects of fuses, but I have been an audiophile for many years and trust my ears, not hype. I sprang for the top of the line, $90 Supreme versions. If worthless, my loss would be limited.

I have installed HiFi Tuning Supreme fuses first in my Wyetech Opal pre, where the improvement was on the order of 10% - 15%; greater smoothness, definition and "naturalness" in sound. definitely woth the $$.

I then installed one recently in my modded Sansui TU-9900 tuner and I would now say the sound is CD quality -- an inprovement on the order of 25%. I occassionally have to remind myself I am listening to an FM tuner. The WFUV NY DJ is talking in the room! The detail on the music is stunning.

This has been my experience. Next up for a new fuse is my W4S DAC2. These fuses are the real deal.

Al,
An update on my AC readings.

Throughout the last two days my AC stays stable @ 119v on five readings and 118V on three readings, all @600V setting. At the 200V setting, the normal fluctuations occur (+ or - .3).

What all this means I can't really say as I don't know which setting is the more pertinent. It seems to be predictably stable.

Neal,

Great to 'hear' you hear a difference. I'm curious now as to whether or not a step up from the HiFi Silvers will make an improvement in my system.

What also gives me pause is the one inside my iMac. I have no intention of opening it up and wonder how much of a weak link it could be considering all the improvements one hears downstream from it.

All the best,
Nonoise

Nonoise, I started at the top of the line, so I cannot answer. My speculation is the improvement would be small but noticeable. Do doubt next year there will be an "Ultimate Supreme." Good luck.

I once replaced a stock 15 amp fuse with an Iso Clean 15 A in a Foundation Research power cord/conditioner and noticed an improvement.

Will there be a new even better fuse on the horizon? I would think there will be,that's the way of all things in this hobby.

I think it interesting, that various fuses measure differently, when their direction is reversed: ( http://www.partsconnexion.com/prod_pdf/hft_facts.pdf ) No- I have not personally experimented with reversing my HI-FI Tuning fuses; being quite satisfied with the improvements in presentation, with them inserted arrow pointing toward load.
