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?

Measurable changes? Huh? Spare me! Nobody measures audio feet. Especially not you. But just for grins, how would you measure the difference between carbon fiber feet and ceramic feet? And between ordinary steel springs and cryogenically treated steel springs? The difference between cones points down and cones points up?
@geoffkait . kosst does not understand how the ear is a measurement device in and of itself. My thoughts are that kosst is listening to his system, and not the music. I know some people, like him, but most I know ( not all ), have been open to listen. But even those folks who do not bother with " my little experiments ", ever doubt what I hear, as many of them have heard my system, and, that says enough.

" I don't know why I keep doing it. It's like some weird compulsion. Maybe my life doesn't have enough fantasy and fiction. I should probably go back to reading Dune. Honestly, I'm really curious why people believe in things that don't exist. "


Very sad I hope you get the help you need for this.
