I am not an EE ( though I do have expertise in other areas of engineering) but what AL says makes sense. I would tend to think that if a fuse did make too much difference in sound quality that this might be an indicator of certain design elements lacking elsewhere.
Just because every component in the signal path can have an effect on the sound does not mean it should.
I'd like to think that my gear performs at a certain reputable level as long as quality components are used (including fuse). SOme audiophile fuses might qualify, some might not, but I do not even want to have to be concerned about how my fuse sounds, just that it does its job reliably and does not negatively impact what the design overall is supposed to accomplish.
