There has never been a reasonable explanation from any "boutique" fuse manufacturer of exactly why or how their fuse may improve the sound of any component...the reason for this is that fuses simply work or don’t, are reliable or not, and can’t influence the sound of anything because they’re fuses...in the midst of the rabid hyperbole surrounding the predatory marketing of expensive pseudo tweaks, simple facts are conveniently ignored. Most reasonable audio geeks (i.e. those not driven by expectation bias, and who can utilize logical critical thinking without faith based mythology) do NOT use Magic Fuses, although those who have invested their tweak bucks in them will generally make claims of improvement so as not to look foolish. Geoffkait’s point about the 80,000 to 50 score is like asking members of a cult how many feel it’s a GREAT cult...Littelfuse and Buss fuses have established excellent reputations over many years, and are used in an overwhelming majority of excellent sounding audio components, and offer products that cost a tiny fraction of what boutique fuses generally cost while providing outstanding build quality and performance.
