Ceramic fuses

I had a couple of SR fuses immediately blow when doing a test a few years ago, and I have never had a decent Littelfuse self destruct or do anything but its job. Expensive fuses don’t and simply can’t make any difference by providing sonic improvement over stock fuses supplied in modern gear, and if people swear by hearing some sort of improvement after swapping out regular fuses for "magic" ones, they’re simply riding the warm waters of expectation bias. Claiming there is some wonderful improvement with magic fuses by offering piles of hyperbole doesn't prove anything but what you "feel" is happening, but that often has little to do with facts these days...I "feel" my cars go faster when they’re clean, but I also know they don’t.

Pure copper has 100% IACS conductivity. Copper allloys have conductivity between 99 and 86% IACS.

Rhodium which is much harder than platinum and palladium, typically 800-1000 HV, and has exceptionally high corrosion resistance. It has
electrical conductivity of 38% IACS. This makes it the most electrically conductive of the platinum group metals. 


Some idiot reads the last sentence above which is made in the context of platinum group of metals, and later thinks Rhodium is one of the best conductors of electricity amongst all conducting  metals.. . 

Ricey, from all the discussion, it's clear that you are referring to a fuse in the power supply part of the amplifier. I've never tried different fuses in that location. I can't opine whether different fuses matter there.

However, I have tried different types of inexpensive fuses in the speaker circuit. Here, the difference was clearly audible. To further investigate this, I asked a musician to listen as I substituted a speaker fuse with a 'wire', in a single-blind test. The musician friend heard the difference every time and consistently characterized the sonic difference, fuse vs. wire. His description matched what I had heard while listening alone. 

There are so many variables that can confound a listening test, that to do a scientifically valid blind test is very difficult. But, if the effect is pronounced enough, a simple test may suffice, like in the speaker fuse experience I had.

In my opinion, try the fuses and see if you can hear a difference. If so, you wind up choosing the one that sounds better to you. Or, you could wind up more confused than ever. Sonic memory can be deceiving. Good luck, and hope to read bout your conclusions.
