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?

Yeah... All that mid-fi like the brands I mentioned. 

Funny thing. Last night I was reading up on the F6 and Nelson pointed out that each unit is meticulously MEASURED to insure every unit sounds the same. We all know how mid-fi Pass designs are, don't we? I like how you cherry picked one phrase to mischaracterize a broader point but ignored everything else you lack the fortitude to address. You're good at that. You didn't understand the meaning of my words and sentences, did you? That's a pretty torpid list of measurements too. If that's all you're measuring the end result probably would be anybody's guess. 
You're rebuttal to my post should have been obvious. Simply point out what characteristics evade a measurement signature. But you can't do that. Just rhetoric and left-handed insults.

The more I read posts, the more I see that you both like to flame discussions. If that is what you both want to do, there’s nobody here that will prevent you (unless forum administrators jump in).

However, please keep in mind that while you have the large number of posts you submit attacking each other, you are also attacking the OP by swamping their mailbox with posts that they probably don’t want. It is also frustrating to other users reading these discussions when the subject matter diverts into a flame war. You’re not just hurting each other, you’re hurting the OP and many other readers. If this is what you really want to do, I can’t stop you, but I hope you are aware of the impacts, especially to newer users who don't understand who you guys are.

No offense auxinput but it appears to me you actually don’t understand the situation. If I have transgressed I’m sure the mods will let me know. It’s pretty pathetic when someone cannot make a declarative statement without someone repeatedly barging in with a barrage of insults. Which is in fact what is happening and what has been ongoing. I don’t believe I ever insulted what’s his name. In case you haven't noticed I tend to pick up a lot of uh, detractors, whatever on this forum and try to deal with them in the most humorous way possible. Of course anyone is free to not read these exchanges. No one is twisting anyone's arm. 
Not really. I'm just asking somebody to prove it and I get stuff like "Morphic fields" for answers.
