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?

it's like power cords, easy to change yourself, so rather than ad cost for a part you might not want, they use cheaper ones and let you choose your own upgrade...or not
It's funny because no one actually knows the answer to the question asked but ...
Again I’ve never heard these fuses and have no opinion other than I don't know...
We want great circuits. Great parts. Looks great. Great service. Great price. Great resale. 
Curious how many have tried the upgrade fuses and preferred the regular ones...I've never tried the fuses...
Sometimes I wish science could explain and measure everything...but probably better that it can't 
And if you decide you like them, others will tell you that you don't. That you just want to spend  more money
If ear witness testimony is often wrong how do we decide what to buy ? I would always prefer the less expensive stuff to sound best and for tweaks and cables to never help. But hasn't  worked out for me...
you wouldn't think a $25 item or one with return privileges would cause so much...at least all you have to do is try them and see if you like them...
We're talking about trying a $25 fuse in a $7000 amp. I don't think anyone's worrying about it...
And there is very much science is not aware of or cannot measure or explain...certainly including sound and human hearing 
that PS Audio piece is a great explanation...so it seems there are high end companies that use high end fuses
Wasting $25 on a $9000 amp...much to worry about...don’t trust your ears !!!
+1 hifiman5 .   he seemed clear that he loved the sound of the more expensive fuses, but as a manufacturer preferred to leave the fuse decision to the owner, though he does not use standard fuses.  I do not own/use aftermarket fuses, have never heard them...
He said in some products he used ceramic fuses, in some circuit breakers.
