Fuses that matter.

After reading much of this thread, the question is: To re-fuse or refuse? I was skeptical about many things in audio that I later came to believe, but this still sounds unlikely to have a major effect, especially directionality. Maybe still worth a try at such low cost.

So just in case anybody still cares after all this, i will recap my thoughts about fuses

1. Fuses clearly effect sound. No fuse, no sound. Pretth clear.

2. A fuse that sounds bad is probably defective and should be replaced

3. If all seems well there are many other things i can do that i understand enough to try to change the sound in a reasonably predictable manner.

4. Changing a fuse might change the sound in a hearable manner but i have no clue what tk expect if i change fuse a for fuse b. I will not be spending any time worrying about this because it just is not important to me.

5. Science is not likely to offer clear guidelines for determining sound of fuses anytime soon. If i pick a new fuse it wlll have to be done based on intuition. I am ok with that. I think i will survive my next fuse change ordeal in good shape.

6. Others will also have to rely on their intuition to make these big life decisions as well unless they know of some reliable scientific basis for picking a good sounding fuse that i am not aware of.

Time to blow my own fuse on this topic :-)

2. A fuse that sounds bad is probably defective and should be replaced

I've had ~40+ Sovtek / EH 6922s over the years and always sound bad compared to the Tele, Siemen, Amperex ... so I guess they were all probably DEFECTIVE.

Also all my stock PCs sound bad compared to after market PCs so I guess they were all probably DEFECTIVE.
... Now it finally makes sense. Many Thanks!

4. Changing a fuse might change the sound in a hearable manner but i have no clue what tk expect if i change fuse a for fuse b. I will not be spending any time worrying about this because it just is not important to me.

It's not very complicated and not good worrying about it, how about just use the one that's sounds better in YOUR component/system? If it doesn't work out and prefer stock, then no Starbucks for a week and sell it on Agon?

Like everything in this crazy hobby, there are no best so just buy/use what is best to you?

Just to clarify, I think that in number 3 you are referring to other fuse-related variables, perhaps unexplainable ones.

Yes. Sorry, I should have been clearer. I was saying that it's possible that there are properties of fuses that account for audible differences among them (assuming they exist) that were not measured by the guy on the the Polk audio forum. And yes, those properties might be not only unexplained but unexplainable. I'm not saying that's true, just that it's possible. And, btw, thank you for your characteristically substantive comments.

Well, maybe I'm wrong. After all, it's merely intuition.

Mapman, you are right relying solely on your intuition is not science at all. It is just a personal bias of no value to others.

I value others' experiences...

I suppose this means that you value others' experiences, so long as they are not Mapman's experiences. Or mine. Or Al's. Or Roger's.

The role of intuition, which Mapman raises, is quite relevant to this conversation. I brought this up in an earlier post...

It's widely (though not universally) acknowledged by people who are both audiophiles and experts in electronic design that, in addition to the Known Parameters that affect sound quality, it is likely that there are Unknown Parameters that affect sound quality. Those Unknown Parameters are either unmeasured or unmeasurable, though that could change with the progress of knowledge, either theoretical or applied.

For those who acknowledge the likelihood of Unknown Parameters, what is the standard by which Possible Unknown Parameters are distinguished from Impossible Unknown Parameters? Since by definition it cannot be the standard of prevailing knowledge, it must be something else. But what? Intuition?

If the answer is intuition, I can accept that. I believe intuition is worth something. In fact, I believe it's worth quite a bit. But I will point out that intuition, even the intuition of experts, has been wrong innumerable times, with consequences ranging from trivial to amusing to catastrophic.

Whenever you are at the boundary between the Known and the Unknown, intuition is a significant factor in judgments about what is plausible, what is possible, and what is nonsense.

I found another set of fuse measurements, this one done by Hifi Tuning. You can see it here.
