I don’t know how to make a good sounding fuse, but I have discovered that a cracked fuse holder can make most any fuse sound bad.

If a system is intended to be used at a level well below its capabilities to deal with current, then it makes building the fuse easier, it would seem. The fuse can be set to pop at a much, much higher current level than any normal listening session would produce. So the fuses internal resistance and any audible compression effects from the fuse beginning to heat can be minimized. I used to have some piezo compression drivers that had little light bulbs in them that acted as fuses of sorts. Instead of blowing, they would take to glowing, which would effectively compress the output to the tweeter. This is fine for a PA system but probably not acceptable to most HiFi enthusiasts.

Doesn’t the power supply include capacitors that store electrical power used by the device, including the capability to supply power for peak demands?  Shouldn’t the power supply be designed so that the current draw through the fuse should never exceed the rated value under normal use?  Otherwise, it would seem the power supply is under designed.  I believe some may be putting too much emphasis on the role of the fuse in the power supply chain.  Obviously, it is essential but, as long as it works properly, perhaps not a direct influence on the sonic end result?

Cleeds...I have extensive personal experience with fuses, including testing a pile of Synergistic Research fuses a few years ago...they were useless and risky (inaccurate  current ratings) junk then, and still are silly and expensive nonsense. Quantum my a**. Call Nelson Pass or Dennis Had to discuss it further. If "magic" fuses actually did what they claim, everybody get on board with 'em....they don't and we're not.

If your "magic" fuses don't do what's claimed, that's snake oil! Fraud! Now, thanks to the work of Tuttle, et al., the template has been created for you to profit enormously from your wisdom while also serving your fellow  audiophile. Here ya' go:

You Can Get Rich From 'Snake Oil'!

I’ve seen so many threads, not this one, where an expensive power cord manufacturer claims are declared snake oil because it measures the same as the PC obtained from Amazon.  People forget that “science” is not a static thing and with time, our understanding of the ‘science’ changes.  So, like the op, I tend to trust my ears, but will admit to the possibility of bias.  The only thing that I know for sure is that when you hear a politician claiming something is “settled science”, it is time to find more tax shelters.
