We Need A Separate Forum for Fuses

cleeds - A primary reason I’ve never experimented with reversing fuses is that I don’t know how to conduct a listening test that would allow me to quickly switch back and forth between the two orientations..... That leaves me with speaker cables but again, how could I quickly switch between two orientations? ....

@cleeds

Understood. I respectively disagree, however, that there is any kind of necessity to do the reversal "quickly".

If the test were simply for your own edification, you could enlist the help of a friend who would perform the reversal (i.e. the reversal or non reversal is blind to you). Granted, it could be a minute or two between each iteration of the test.

Keep in mind though that many folks have expressed a "major" difference. In these cases, I humbly submit that if in fact there is a major difference, it should/could be detected regardless of the test methodology and how long or short of time elapses between each test.

For example, if I play a Bob Dylan song and once complete I then play an Amy Winehouse song, I might say "they sound different" and in fact "they sound overwhelmingly and obviously different". In this case, it wouldn't matter that Amy Winehouse began playing 1 millisecond, 1 year, or anywhere in between after Bob Dylan. I’d tell you, *one hundred percent of the time* - as in never wrong once - whether or not Bob or Amy were the artist being played.

Therefore, those who purportedly can hear a "major" difference when a fuse or wire is reversed, should also be subject to this same - and very simple - test, irrespective of duration of time between the first listen and subsequent listen.

You're free to disagree, but there's a lot of research on valid listening tests that conflicts with your claim.

I think the changes that might result from reversing the orientation of a fuse would be a lot more subtle than discriminating between Bob Dylan and Amy Winehouse. The test you're describing is nowhere near rigorous enough to reliably reveal such differences, and I suspect you know that. 

Can someone please remind me what the topic of this thread was !!

Hi @cleeds 

First, my apology as I meant to write "respectfully" instead of "respectively". No matter, you get the idea :)

I think the changes that might result from reversing the orientation of a fuse would be a lot more subtle than discriminating between Bob Dylan and Amy Winehouse. The test you're describing is nowhere near rigorous enough to reliably reveal such differences, and I suspect you know that.

Consider the operative word you are using - "subtle". Now consider many folks are clearly writing "major", "not so subtle" and other descriptors instead of the just the word subtle. I see/hear nothing wrong with the "blinded" Amy > Bob > Amy > Bob test I describe. In fact, I would have to think you and others would *want* to do a blind test in the manner I describe, even if merely to substantiate your belief. This is what I did when I purchased a DAC. Why wouldn't you/others do this when reversing a fuse/wire?

Understood, but as I explained, a lot of research shows that quick switching is required for a valid listening test.

In fact, I would have to think you and others would *want* to do a blind test in the manner I describe, even if merely to substantiate your belief. This is what I did when I purchased a DAC. Why wouldn’t you/others do this when reversing a fuse/wire?

I've already told you: I don’t have a belief. I haven’t switched the orientation of a fuse or wire, so I have no reason to test it.
