McIntosh fuse changeout to make better sound

To whom it may concern:
I trust what I hear. I do not have to "prove"anything to anybody, about anything.
Several of you embark.on a mission to prove a negative.
Good luck with that..
how do you "prove" what someone did or not hear??
Than you call someone else arrogant?
wtf????, get real.
Your results may vary..that does not trump; my experience.
It only makes me believe, I am dealing with some kinda dolt.

You hit the nail on the head: arrogance. Rude, presumptive, ignorant and stubborn arrogance. Each adjective carefully chosen for accuracy. Rude: they butt in where no one wants to hear their blather yet again. Presumptive, they presume to tell us what we hear. Arrogant, what could be more arrogant than to tell another individual that YOU know what THEY can do. Ignorant, because virtually every single time they haven't tried and so literally do not know what they're talking about. And stubborn, because they keep at it no matter how many times or how clearly its explained they are full of it.  

You can see I've been around and have seen it replay over and over again like Groundhog Day without the humor. They just die over and over again, only never ever do they learn anything, and in the end they for sure don't get the girl. I just thought it worth pointing out that even a new guy with 7 posts can see clearly just what is wrong with them. Why they can't see it, that is the question.

You are right, the first thing I met with was rudeness.It clued me into the scene, immediately.

If someone spends north of $100 on a fuse, pops it in and hears a difference I have no doubt that person is telling the truth. But that does not mean the fuse actually did anything.

All I can say is that when I make a system change I live with and at some point make a determination as to whether or not I think it sounds better. I’ve noticed with audio cables that cost above a few hundred dollars or so, price no longer determines quality or better sound any more than price makes one wine varietal taste better than another of the same varietal-- at a certain level of quality-- there’s just differences-- like the flavor notes between those wines, and you go with what you like. Is it better? To you maybe, but in truth, they're just differences, not better than or worse than.

Some people that think a $100,000 amp is always better than a say $25,000 amp because of the difference in price. They are, IMO, deluding themselves because of the general prejudice that higher cost equals higher quality-- at a certain level in almost all things, it just ain’t so. A $100 fuse is not likely any better than a $3.00 fuse. 

Tis called a blind test. You didn’t meet with rudeness your very first post was rude. Does someone have anger issues?

how do you "prove" what someone did or not hear??
