The advantage of LittleFuse is that their fuses are real, tested, certified by real testing labs. Audiophile fuses are generally not tested by anyone and would likely fail those tests. I read a test report on the ones from Germany. The report was a joke, meaningless, proved nothing.PADIS fuses are UL, PSE and SEMKO approved, and are German made. I think you need to broaden your knowledge of what's out there.
Basing your rant on aftermarket fuses on one brand that you heard about doesn't make you an expert on them. I've tried 3 different brands and they all have their own sonic signature and I've yet to build an amp and lord over people with what I know about them.
You can come across as very condescending.
All the best,
