Definitely not promoting the idea that these hi dollar fuses present "value". That being said, it should be easy enough to test different fuse types on amir's test bench. Ceramic, sand filled, and clear glass fuses would be a good start. Low and high values along with fast or slow blow could be tested. This would provide some hard data, which may or may not be meaningful depending on where the fuse is used. A main input power fuse has little chance of making an audible difference. If you doubt this, remember the audio path loop is primarily through the final capacitor in the DC supply. A fuse to protect a speaker tweeter would be a more likely problem for something audible.
Not saying this would stop speculation, beliefs, expectation bias, etc. I am saying some hard data would be nice. I have not searched ASR to find out if this has been done - too lazy.
