What are fuses used for?

It’s explained by the fact that people spending 150 bucks on a fuse really NEED to hear an improvement or they feel like they’ve been duped, and also feel the need to join a support group (like the ones here) for the same reason. Most audiophiles and gear manufacturers (like Roger Modjeski) don’t care at all about "magic" fuses...what explains this?

No, it's not BS. It's being able to hear and appreciate the difference. 👍
By the way, who's been busy getting posts deleted? Someone with their fee-fees hurt?

All the best,

The naysayers must be studying the script of 12 Angry Men. “You can’t prove it!” “But you said we can forget about all the other stuff.” “How can be be so sure?! “I’m telling you, some of you people in here must be out of your minds.” “Don't give me that. I'm sick and tired of facts! You can twist 'em anyway you like, you know what I mean?”

Nope, it's not BS. I think its more system dependent than anything. What I'm finding through conversations with other members is that some tweaks, like those wall socket plug-in thingies (I forgot the name of them again), counteract other tweaks. Either that or its a hearing problem of some sort. Or maybe we're just listening for different things? 

On proving it through measurements, I've personally measured each upgrade through one of the most accurate measurement devises known to man ... the human ear. Not as good by far as the ears on dogs, but good enough to be used throughout the ages for a variety of things, including the preservation of the species.
