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?

And lets not forget the little blind naysayer people following the little blind nonbeliever sheep. Geeze, and now there are little minds, little statesmen, and the philosophers and divines are, I’m guessing, kind of little too.

None so blind as those who will not see. 

An ordinary man has no means of deliverance.

if _there_ is a large sample consisting of people whose subjective experiences all have common descriptions

then that is useful grist for the hypothesis forming mill, but not what any scientist would call data

if you then make sure the sample is statistically valid and uses relevant methodology (such as double blind testing) THEN you have real data  (and would next want to find the mechanistic reasons for the difference)

the former might be akin to what we'd call clinical experience


You obviously don’t understand testing, evidence or the fallibility of blind tests. Of course that’s nothing new. Pseudo skeptics have been threatening audiophiles with their silly blind tests for ages.

Costco_emoji, let me know when they, whoever they are, can measure sweetness, air, glare, musicality, presence, music that gives you goosebumps, venue recognition. No need to reply, it's only a rhetorical statement. 😛
