Fuses that matter.

Al,

Just for the heck of it I went and got a multimeter and here are the preliminary
results:

Time: 7:45 pm on a quiet Sunday, usual time for listening.

At the socket:
a steady and constant 119 @ 600V
fluctuating constantly from 119.7 to 120.3 @ 200V

From the Brick Wall Filter:
a steady and constant 119 @ 600V
fluctuating constantly from 119.7 to 119.9 @ 200V

Everything I use is plugged into the Brick Wall Filter, so I guess that it's good that I at least have that in my system.

I'll take steps to measure more tonight and through the day tomorrow and get back to you with the results.

All the best,
Nonoise

Almarg, I borrowed a voltage tracking machine from a friend in EE and checked my voltage continually for two weeks. I got occasion drops from the typical 122.4 volts. In Texas the electric companies are accustomed to heavy use in the heat. Last year they lost a good deal of their reserve as they had exposed water pipes that froze in the winter and were being repaired. Some planning! But here we were not subject to the black out that Texas inflicted on New Mexico.

I, at least, don't have any pattern of when the system sounds better.

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.
