@wolf_garcia , well, at least you've tried one.
I'm curious how many naysayers in this thread have actually TRIED an audiophile grade fuse. Probably in the neighborhood of 10%, I'd guess.
I do find it interesting that some people (myself included) absolutely can hear a difference and some people can't.
All I can suggest is "try one". If it works for you, great. If not, get your money back.
