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?

...  what you think you're hearing IS pure belief and NOT proof in the slightest. Such a semantically obvious fact illustrates how deeply confused you people are about the difference between belief and facts ... I've never seen any hobby embrace snake oil like this one! Not even close! The faith people here place in various tweaks that do nothing can only be compared to the powers the superstitious attribute to magic talismans ...
Thanks for sharing your deeply-held faith-based convictions. I think many of us had already figured them out, but this post makes them more clear than ever. The only part that I don't understand is why you're so angry with so many on this forum. Most of us are just here to have fun, it seems. What are your motivations? Is it just to proselytize? 

Frankly, and I certainly have no animosity towards anyone, nor intend any disrespect, but I disregard with prejudice what ANY pseudo skeptic, naysayer or Crusader Rabbit presents as evidence or proof for any controversial tweak, including fuses, fuse directionality, wire directionality, etc. Who cares? Anybody can dream up some bizarre case they think will turn the tide. It’s actually not (rpt not) up for debate. Case closed. Like the mind of Crusader Rabbit. 🐇

The whole idea that rotating the fuse improves the sound, and is therefore the real reason audiophiles hear improvements when flipping fuses, is preposterous on its face, anyway. Because the odds are 50-50 that the sound would be *degraded* by rotating the fuse. Besides, if someone can’t hear the difference in fuses or in fuse direction, I certainly don’t believe they can hear fuse rotation. It doesn’t make sense. Judge Judy says if it doesn’t make sense it’s not true. Furthermore, we already know that fuses measure according with the direction they are oriented in. Case closed. If you can’t hear that’s your problem. Better get it checked out. 
  • It is not about facts.

Yep. That’s it in a nutshell. Cheers! Too much time spent talking about fuses. People will think and do what they will and are not likely to change, especially the older folks like me.

Can I quote you on that? 😀 Next to, “Only quote facts,” yours is my favorite.
On a speaker thread, someone recently spent $1300. on a pair of speaker isolation products, claiming it took his system to an extremely higher level of musical satisfaction. I can believe it. It is still amazing to me, that people like kosst ( a troll imo ), requires scientific facts to back anything up. A long time ago, Julian Hirsch, compared, by electrical measurements, an inexpensive japanese receiver to a relatively expensive amplifier, at that time, showing how close the two products were. I do not recall if he " listened " to these two products, but I do believe he made the comment, that if they measure the same, they must sound the same. Some people need to wake up, give things a try ( a little fuse test ), and trust their ears. If they are NOT WILLING TO TRY AND LISTEN, how can they make a comment at all ?
