To Fuse or Not to Fuse... That is the question!

So like 20 / 25 years? Awesome. There should be lots and lots of properly run tests that show that people can pick up the audible differences right?

What's that you say ... no you can't provide me with any links other than some old digital stuff where RCA plugs were used for controlled impedance signals and you ended up getting transmission line effects and jitter?

Really ... 20-25 years ... nada. I never would have guessed 332.  No worried, I think jae48 said he would like to set up a room at an audio show so that we can run some double blind tests like this. I am willing to put in some good money, heck I would put up a grand. You?  Wouldn't you like to, for once, be able to point to a large listening group test that clearly, in front of pundits and naysayers alike proved what you are claiming?

Yes, MFRs in audio use cryo. Why ... people will pay for it. In the business world that is pretty much the best reason there is. Spend a few dollars to drop in in liquid nitrogen, charge 50x your cost. The brilliance isn't in the engineering, it is in the marketing.

The only trap you fell into is assuming you could get away with posting marketing fluff and calling it engineering.

In a good transparent system... fuses influence the sound in a way that can be heard. Some fuse designers learned ways to make the sound more pleasing to the ears. Fuses simply have an effect on what plays through the speakers.  There is no perfect fuse,  anymore than there is a perfect speaker cable.  They all influence what is heard.  We choose what we like to hear. 

100,000 fancy fuses sold to date so it looks like it’s you against the world Mr. Smarty Pants 👖and looking into my crystal ball I you can probably add at least another 50,000 for the new 🍊 fuse. Snooze, you lose. 😴 By the way you didn’t interpret the data correctly. Your humble narrator did, though. 🤗 Be that as it may, as I said there really isn’t any debate any more. But you’re welcome to carry on.🕺🏻 You aren’t the only stubborn mossback in town. 

You are confused because GK keeps parroting that the energy is only conveyed from source to load, hence the fact it is AC makes no difference as the energy is unidirectional (even though current is bidirectional)l, and uses this as a justification for fuse directionality.

"You can ignore the current traveling in the direction away from the speakers, I.e., toward the wall, since that direction of current flow is not (rpt not) audible."

The first statement about energy transfer direction is correct, as the energy flows towards the load along the Poynting vector. The second statement is not correct. It sounds right based on the first statement but it is not.

What GK fails to realize is that the Poynting vector is the spacially integrated cross-product of the E (electric) and B (magnetic) fields, over the WHOLE circuit, and that everywhere current is flowing (in a wire), there are E and B fields, meaning that EVERYWHERE current flows impacts the Poynting vector. If you didn’t have current flowing both towards the speakers AND away from the speakers, you wouldn’t have E and B fields and you wouldn’t have a Poynting vector and you wouldn’t have energy transfer from the source to the load. The current traveling to the speakers and away from the speakers are equally important in defining the Poynting vector.

At a macro level, the Poynting vector is the same for both polarities of the AC signal, as the E-field is structurally the same, but as opposed to that justifying that the fuse is "directional", the opposite is true.

>>>>There you go again putting words in my mouth, Mr. Marty Pants 👖. I never said any such thing. Maybe you should try keeping a log. In fact what I said somewhere along the line is that energy is a scalar quantity, which means it has no direction. Follow?
