McIntosh fuse changeout to make better sound

Fuses will never effect the sound of any component unless they blow, as that's their job. Period.

That's the question I often ask when this nonsense pops up...if magic fuses provided even a fraction of the benefits claimed by bloviating posters offering hyperbole laden claims these things would garner universal acceptance and be used by every serious manufacturer and far more audiophiles. There's the rub...

For marketing purposes, it's a great idea to produce a product that claims efficacy and back it up with hyperbole with a qualifier like "if you can't hear a difference you or your system is/are inadequate somehow." The fact that ridiculously expensive "magic" fuses are generally ignored by the vast majority of audiophiles and component manufacturers should tell you something. And it's worth noting that no component I know of claims that its internal wiring (including the wiring immediately after the fuse) is utilized with any thought of wire directionality (a box of wire directionality chaos! Oh no!), except perhaps internal speaker wiring, although that's generally not mentioned either.

I did a thorough test of SR fuses a few years ago and they made zero difference except when they blew...zero...which makes sense as they're FUSES. Otherwise hey, they're great...*yawn*...

I prefer a "Methode Champenoise" approach to gravitational influences on fuse performance which simply requires giving every fuse (every one...open that lid...get in there) in your system a quarter turn at least once a day. If you don't at least try this you simply cannot comment on its efficacy so please, no comments.
