Neither Decware or PS Audio endorsed any one brand ( actually PS Audio did mention a specific brand in their literature but I don't remember which one) but advocate trying differant brands to obtain the sound you like best. Paul McGowan wrote an article specifically about fuses and how they effect sound quality. I don't have the necessary knowledge to know if or why they work, but I'm willing to put my faith with the many here that love them and more importantly the men who designed my equipment endorsing their use.
My intention wasn't to belittle ptss's response, my response was in jest. My apologies if it came across negatively. I agree that fuses are put in a device only for safety reasons. Pauls article mentions how when designing one of their amps the prototype didn't have a fuse and when one was added for production the sound quality diminished to the point they had to make some design changes to get the prototype sound quality with the fuse. I checked with both manufacturers about fuse values and both said moving up one value wasn't a problem but going higher than the 1 amp for the Perfectwaves wasn't necessary, so I didn't higher values for them.
