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?

I just installed high end fuses in my scoutmaster motor,and i must say it runs way better, or maybe not, wait,theres no difference.
Hey, look on the bright side. At least your motor didn't start running in reverse. Or did it? ⚙

What??? You didn’t hear insane depth, expanded soundstage, instrument separation, dead center midrange and everything more cleaner.....

If you didn’t then you must change the direction of the fuse :-)
Put the PADIS fuses in my class D monos. They definitely sound better already. Better clarity and imaging, smoother mids, cleaner bass. Very happy with these guys.

I'm sure it's just because I cleaned the contacts when I changed fuses. That and a bunch of expectation bias. 😝
