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.

Ok, this time I'm serious...

In addition to the Pass amp I used for my fuse experiment, I have a Parasound Halo amp that I use for home theater. Yesterday I opened the Parasound and removed all the fuses, 6 in total. First I cleaned the endcaps with Cardas contact cleaner and then I polished them with Progold. I reinstalled the suckers and fired things up. I thought I noticed a slight improvement, though I may have been imagining it.

Then I decided to clean and apply Progold to every contact in the system, including the contacts on the power cords and IEC inlets. Now THAT was audible.

When it comes to electronics, especially contacts, clean/conductive is always good. Nothing crazy there!

Well, I hate to judge before all the facts are in but I suppose there is some possibility that the unclean contacts masked the results of the fuse tests.

That occurred to me, Geoff. But that ambiguity is present in EVERY listening test. In other words, when you fail to hear a difference during an A/B, there are ALWAYS three possible interpretations...

1. There is no difference between A and B.
2. The system is not sufficiently resolving to hear the difference between A and B.
3. Your brain is not sufficiently resolving to hear the difference between A and B.

If your A/B testing is limited to a single system, then it is literally impossible to know which interpretation is correct. The only way around this is to (a) change an element of your system and test again, or (b) listen to the reports of others who have performed similar tests on their systems. I tend to do both.

But I dread the idea of another fuse test. I think I will just leave in the fancy fuses. After all, they look pretty.
