Synergistic Red Fuse ...

More noble sound? What the heck is that? Sweeter treble? Lower and more saturated bass? Unlikely, or more to the point, likely having zero to do with the fuse, but if these things did occur I want to know WHY the fuse made this possible. I'm reminding my fellow posters to consider the fact that a fuse is NOT an "active" component…it's a fuse…allowing electrons to pass to and fro until it melts due to an otherwise unforeseen emergency. Asking this "why" question is bullying only to the extremely insecure or those who've invested themselves emotionally (and financially) in this nonsense, and again, there's nothing negative involved is posing the question. Incidently, this STILL remains unanswered, which should be at least of some interest to anyone considering buying any expensive but relatively suspicious tweak. I hope this gentle and considerate post doesn't push anybody into emotional overload.

Now all you cheap skeptics ain’t got no excuse. Deluxe Create Audio Nano fuses direct from China $9 each. Select your own rating. eBay to the rescue! Packet delivery from China $2. Cannot beat with stick. Tell all your friends. At that price even Wolfman will be able to hear them. Well, let’s not push it.

sidebar to Wolfie: it figures that the term sweeter treble is not in your vocabulary. What do they teach you at audio engineer school, anyway?

I posted 'auxinput's' contribution from another thread earlier about how the signal is about 98% A/C voltage and no one has shot that down yet. Glossed over maybe, but not disputed. 

Taking that into consideration (at the very least), doesn't it leave open the 'weak link' aspect of the fuse? Just to consider it doesn't mean you've fallen prey to some devious aspect of marketing. Granted, there's a lot of hype that's right up there with the Amazing Randy but THAT'S the marketing side of things. I can see where everyone's BS meters go off when they read the 'science' behind it but that's a case of throwing the baby out with the bathwater. 

Like teo_audio points out: a solid copper bar will ruin you forever once you've heard what it can do and have to put that fuse back in. That tells me that a better made fuse should improve the sound. I could care less about the theories behind the marketing claims. I just know better made fuses work because I've heard them for myself. And  yes, they shouldn't cost as much as they do. I can see an argument for that, and I'd support it, but not the efficacy of better made fuses.

All the best,

I posted ’auxinput’s’ contribution from another thread earlier about how the signal is about 98% A/C voltage and no one has shot that down yet. Glossed over maybe, but not disputed.

The salient paragraph of Auxinput’s post, which you quoted in this thread on 3-9-2017, was:

In a power amp circuit, the output transistors have to create massive gain (turning a 1V input into something like 15-100 watts or more). It has to use the A/C power coming in to create this voltage, so your signal is actually something like 98% A/C voltage.

Obviously just about all of the power that is put out by an amplifier (or any other AC-powered component) is **derived** from the AC power that is provided to the component. However, saying that does not provide any kind of meaningful explanation as to how an AC mains fuse may exert an audibly significant effect on the output signal of the component, given all of the intervening circuitry that is present, that is (or at least should be) designed to minimize the sensitivity of that output signal to differences in the incoming AC. And it certainly does not provide such an explanation that would stand up when analyzed quantitatively, or that can even be analyzed quantitatively. Or (as I’ve said in earlier posts) that would explain the high degree of consistency of the reported benefits, among components that are completely different in design, that perform completely different functions, that are used in very different systems, and that are powered by AC having very different voltage and noise characteristics.

Simply asserting that a fuse may be a weak link in some way is not an explanation that would be viewed as meaningful by the court of electrical engineering. Which is not to say that a ruling by that court is definitive. It is to say, however, that the proffered explanation is not definitive either, or even meaningful.

Al, you have the most gentlemanly way of refuting. It's not absolute and not insulting: a trait we call can benefit by.
