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 did have a conversation about fuses with another well known amplifier designer, Steve McCormack, when I need to replace fuses in my modified DNA-1 Deluxe. The fuses blew because of a stupid mistake on my part not on any deficiency with the amp. Steve had a clear preference for HiFi Tuning Silver Star fuses which at the time of the conversation were being sold at a discount due to being replaced in the HiFi Tuning line by the Supreme fuse. Steve mentioned that he tried the Supremes in his gear but preferred the Silver Stars.

So now we have evidence that was routinely decried as lacking that some engineers know that fuses make a difference and now it's turning into a meme that we need engineer naysayers to battle it out. 

This is a fool's errand. It looks like anytime something valid is brought up, it's pushed to the side and new demands are made.

It wouldn't surprise me that there's a whole bunch of engineers who know that fuses make a difference but choose to stay mum on the topic.
With social media being what it is, what's to prevent trolls from following and slandering engineers on their products sites, personal forum sites, and the like? I can easily see some here doing just that, and they'd do with with glee. I, for one, wouldn't want them to follow me anywhere save for this site. It's bad enough as it is.

All the best,

Ya know, if fuses did make any difference engineers would use relays and breakers. The fact a few makers choose to pander to snake oilers it's proof.

Again, proof that once something valid is established, it's off on another laughable tangent we go. Where, in that video, did Paul McGowan pander to snake oil? Or Steve McCormack for that matter?

Exactly nonoise!  My experiences with Steve McCormack have always been based on what is heard not a belief, myth or fable. He engineers a solid design and chooses each capacitor, resistor, wire, etc. to maximize the sonic performance of his gear. I wouldn't want to own components from designers that would do otherwise.  

My guess is that a great number of equipment designers take wires, fuses, directionality etc. into account.  As Paul McGowan said on that video, He's an audiophile too!
