Why don't amplifier Companies use high end fuses?


My equipment - Raven Integrated Reflection MK2 tube amp 58wpc. / Lumin A-1 DAC Streamer / Synology NAS / Isotex Aquarius Power Conditioner / Furutech Rhodium Plug / Sonus Faber Amati Homage Tradition speakers.  

I have read thousands of comments on upgraded fuses improving the performance of sound.  I am very open minded but not sold either way.  So, the question I have is....if fuses were so important, than why don't Amplifier companies all install them as OEM equipment?  To me, if they are as good as people say, that would provide companies who use them a competitive advantage?  

Every High End Audio store I go to in Phoenix have told me it does not make a difference and is a waste of money.  For the record, I have fuses purchased at an automotive store for under $10 and I think my sound is awesome.  The Company that built my amp tested the Synergistic Fuses and he emphatically said there was no difference.  

If I were to try a fuse for fun, given my equipment, what would your recommendation be to try?

That’s weird. I didn’t even mention quantum mechanics. Yet kroost_emoji has some ridiculous argument involving quantum mechanics. My arguments, today at least, involve physical reality, physics and human perception. Audio forums can be so unpredictable! Please don’t put words in my mouth. Your name dropping is duly noted.

confucius say man who argue with himself has captive audience.
@geoffkait - I totally understand and agree. I have read other posts in other threads from this particular user and I am constantly asking myself  "what the @#$#$ is he talking about?!?!". Hence my assumption that this is just a troll looking to incite argument - trying to find any sort of technical hole in someone’s comments to dig into and expand. I invite all others just to politely ignore these and not chase down a rabbit hole after any sort of convoluted and confusing theory -- without personally attacking any character of any user.
Since the history of mankind, starting with the pictures on the walls of the caves, the hieroglyphics of the ancient Egyptians, only 10 people have been concerned with the directionality of wire.  This would be geoff and two other people.  Most won't see the humor of me working in that Geoff has a penchant for calling others schizophrenic.  C'est la vie.  In any case, I have admired Geoff for being the Johnny Appleseed of directionality, actually, kind of a Davey Crocket when you think about it.  Let's just say it, going where no man has gone before.
