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.

Knghifi, I did try them. I found them smeared and midrange oriented.
It sounds like the fuse is not broken in. When new, it sounds too sweet with emphasis in the mid but never smeared in my system. It takes 100+ hours for a fully break in. I have several friends using them with the same positive results.

They had at least a hundred hours on them.

I'm sure different fuses have different electrical properties that can affect the signal passing through it.

Personally I will not lose any sleep over fuses though. There are many other more straightforward ways to tweak the sound as needed.

Might have to consider getting into the audiophile fuse business though. $$$$$$$$$$$s

Goldeneraguy, I agree. When I was first told to change the direction of a fuse and it made a big difference, I had to face the fact that I had no clue why. Since then I have just accepted the reality that there is no explanation in EE to account for this. This, of course, means that there is no predicting which fuse or which direction will be best. For a long time I used IsoClean fuses that indicate with an arrow which way the fuse should go. Initially, I did listening tests to see if the arrow was going the right direction. It always was. Then the question is which end of the fuse is directly connected to the wall. The arrow should go from that end. Of course, with no arrow, you have to try both ways.

Well, there must be an explanation if a difference is heard.

MAybe the fuse line material is not electronically consistent from end to end resulting in non symmetric electrical properties that come into play when direction is switched?

When a fuse blows, the gap can seemingly occur anywhere,wherever the conductor is "weakest", and commonly towards one end or the other so that would be consistent with this theory.
