Furutech fuse


Back story. I find the prices of Synergistic fuses extortion. Like someone charging $100 for a cup of water in the desert. The product may have value as a tweak, the materials do not justify the price to me. 

However, ever the tweaker, I succumbed to buying a $40 Furutech 20mm 4 amp fuse for my preamp.

It’s rhodium plated OFC.

I tried it in both directions. Yes, it sounded more coherent in one direction than the other. I ran it for about 10 hours.

I did not like the sound. Etched and dry with reduced bass. I swapped back the original.

Because the plain fact of the matter is nobody really knows why hardly any of this stuff works. If they did they’d all be doing it. Like take aerodynamics. Pretty much everyone knows why airplanes fly. The result is they all look so much alike you’d have to be an expert to tell one from another. With audio its like they still haven’t figured out if three wings are better, or even if we need wings at all.

>>>>Speak for yourself. I think what you probably mean is pretty much everybody takes airplanes and flight for granted and don’t think about it much and only a few people actually understand flight dynamics, fluid dynamics, propulsion and aerodynamics.
Millercarbon, the problem for me is that I have a background in electronics, and I know not so much the specific explanations, but that there is an explanation. There is always one or one forthcoming. Is it a physical phenomenon or a psycho-acoustic one? Is it something few of us in the forum are qualified to understand? Maybe only a few engineers at Synergistic know? Perhaps they came back from the future with a new compound. We know silver conducts better than gold. We know about surface conductivity and long crystals in copper wire. And we use that knowledge to make better sounding components. In the case of the fuse, they may be simply exploiting the fact that thin wires under tension vibrate and that the junctions in a fuse cause ionic collisions or whatever, and they are merely addressing these factors. And it is wonderful that they are. But, to the best if my knowledge,  they are not forthcoming about the construction or the materials or the mechanism, and that makes me suspicious. 
I don’t get what all the angst and mystery mongering is all about. Aftermarket fuses have been around like forever and and well understood. In fact there really aren’t any mysteries at all, as far as I can tell. They’re not forthcoming? Huh? Most fuse makers go to some lengths to describe exactly what’s involved. Cut me some slack, Jack!
@geoffkait  - I think he was really talking about the folks at Synergistic Research.  And no, they don't reveal what they use in the fuse.  All they do is say "this fuse is so great it rocks!!".  However, I did go to the Synergistic room at RMAF (20 minutes I will never get back from my life!!), and I firmly believe there is a significant amount of expensive "snake oil" in the Synergistic products.  That being said, their fuses are doing something different than stock fuses and many people like them.
Huh? Synergistic explains very clearly what they do to their fuses. I’m not sure I sign up 100% to their explanation, but at least they tried.
