Synergistic Red Fuse ...

"Anyone tried the fuses filled with bees wax? $175 per fuse."

One cannot legally sell a fuse filled with bees wax, nor modify a fuse to such an extent, in such a way --- that it violates code and original certification specs. 

You can put just about anything in a piece of gear, but you can't mess with the fusing nor AC power input systems and hardware. The legal system and the certification boards of the government will come down on that like a ton of bricks, for all the right reasons.

"Yes you better move up in amperage as they seem to have a tendency to blow if matching the current fuse in place."

One should try to not change the fuse type nor current handling value (upward).

This is violation of code and design, and will cost you the validity of house insurance, contents, etc. It can open a world of hurt in the legal end of things if something should go awry.

I can say that I understand and believe in the idea and reality of ’audio’ fuses’. Importantly, though... fuses are legally and otherwise, in their certification and use --- wholly sacrosanct.

I’m willing to go as far ...or in most cases, much further down the road for better sound, than the folks reading this. However, I do not screw around with non certified, non tested fusing, nor fuse type or values.

Power rail fuse on a power amp? maybe. But only if the AC power fuse in the amp’s AC inlet....is proper in type and value as to the original specification.

As long as the audio fuses in question are definitely of a known proper certification, and correct amperage and type...then it’s a go, when used for the AC power on the given gear.

They work because fuses are the biggest bottleneck in the power supply. Bypass the fuse and improve the sound far more. I am not saying do it, but the point is any fuse is the weak link in the power supply. That tiny, tiny, thin wire of a fuse placed in an environment needing a more substantial gauge of wire is a certain and easily understood bottleneck. SR should also make a better fuse holder as this is yet another bottleneck. So anything that helps that tiny,  thin wire act more like a 14 gauge copper wire will improve things. That is no doubt what they did as well as others. This gets us closer the mystery of the SR or any Aphile fuse.

Not sure I agree with your detective work, no offense. Because all of the aftermarket fuses employ thin wires (just like the stock off the shelf fuses) - with obvious higher performance - I suspect we can rule out thinness of the internal wire as the bottleneck. I suspect the real answer has more to do with purer metals for the wire and the end caps, vibration control and RFI/EMI absorption AND last but not least wire directionality.

have a nice new year

I think there is something that should be mentioned.  It's judgmental to talk negatively about people who may not think that buying 10 or 15 fuses is worth the sonic improvement and may experience "cognitive dissonance".  Some people may have more important things they value than to spend their hard earned on fuses.

And lets be real, soon there will be a SR platinum that "blows away" the SR blacks that "blows away" the SR reds that "blows away" whatever the one was before it.

I have been member of A'gon for longer than most, and have found this thread fascinating, thanks oregonpapa.  In the end, it is the believers versus the non believers.  The believers are well respected, but the non believers think they are perhaps experiencing at the worst mass hallucinations or at best the effects of cleaning their fuse holders.  While among the non believers are some of the most technically respected on this site, it is obvious to the believers that their systems are not resolving enough or their hearing not up to par to appreciate the improvements the fuses make.  And of course some of the more socially polite non believers whose name we will not mention (ALMARG) are allowed to present their cases with diplomatic immunity, others of not as polite stuture have been cast off the island.

May we all be happy and healthy in the New Year!
