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?

@kosst_amojan this is a medical condition please ask your parents for help compulsive behaviors can really ruin your life there is no need to suffer alone there are many ways you can be helped with this. Since you understand that you have these  compulsions you have already made a giant step towards a resolution good luck too you!
Not sure what provoked all the personal insults and attacks, but I'm not dealing with it.

I've made this point before, but I'll make it again. Anything that can be heard can be measured. I don't understand why some of you think that there are some characteristics in audio that don't have a measurement signature, but that isn't the case. You people attribute qualities to a fuse that most definitely would reveal themselves through a spectrum analyzer. But they don't. One can only conclude that's because it makes no difference at all.

Perhaps because we want the protection a properly designed and manufactured fuse provides, you know the ones by Bussman or Littlefuse (sic) for an example.


>>>>>Wow! Another manufacturer checks in.

“We don’t need any of your stinking tweaks!”

“We want customers to hear the pure sound of our products.”

“We don’t fall for snake oil. Only solid engineering here.”

😛

Idle question: Why not simply improve a “properly designed and manufactured fuse?”  Hel-loo!

>>>>>Excellent example of a Strawman Argument. I.e., logical fallacy. Most who try them hear them. Capish? Actually, fuses DO reveal themselves through a spectrum analyzer. You yourself claim anything that can be heard can be measured. Hel-loo! Same for cables. Fuse and cable directionality shows up on a spectrum analyzer, too. You’re grasping at straws.
