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?

As for measuring, I had to turn down my volume by 2-3db because after changing directions, it was too loud.

That being said, I also have experienced the 2-3db effect when changing fuses or power cords or op amps.




Really??? 2-3db difference in absolute volume because of changing the direction of the mains fuse? I’m stunned and speechless.

The "sound" of a fuse (piece of wire) is a tricky subject indeed! But first we must define (and agree) what exactly is "sound". I propose that "sound" is our brains' interpretation of pressure waves in our oxygen/nitrogen atmosphere impinging upon our ears (acoustic sensors). From this basic proposition we can then make further inquiries. The old debate going back 50+ years was the "sound" of tubes versus transistors. I propose that neither has a "sound". For either to work they must be used in a circuit (amplifier). And then connected to a wave-pressure generator (speaker). Only this coupling (amp/speaker) produces "sound" (pressure waves). Neither the "circuit/amp" nor the "wave pressure generator/speaker has an INTRINSIC quality called "sound". Only by considering the amp/speaker as a SYSTEM can  we make progress in our understanding of the phenomenon called " sound"! END OF PART 1: Next, some of my subjective observations on the controversial subject of fuse (wire) "sound".
Here is an interesting aside: John Bedini (one of the premier circuit designers) came to believe in the directionality of resistors. He claimed to have invented a method for measuring this property and using it to select resistors for his amplifier circuits! If true, this would qualify as a major discovery in Physics!
Well, as much as I hate to toot my own horn 🎺 I have been saying all along that because all (rpt all) wire is directional, not only are fuses directional but also resistors, capacitors, transformers, and obviously cables and power cords. Also, internal electronics wiring, internal speaker wiring, crossovers including wiring and you guessed it inductors and capacitors. Gee, what about house wiring? Mr. Bedini might have stumbled onto something. 😳 A major discovery in physics, indeed!

There you go again spouting meaningless platitudes. Nothing in this hobby defies the laws of physics. Plenty of people are skeptical of things that don’t actually exist. I like those people. I get worried when I’m around people hearing things that can’t possibly exist.

Calm down, it’s only an expression. But judging from your reaction 😡, an expression that actually has some meaning, you know, inasmuch as naysayers like yourself keep repeating the same mantra: this directionality phenomenon can’t possibly be real, it’s not possible and it disobeys all known laws of physics and electronics. You like people like yourself. 😡 😡 😡 12 Angry Men. 😀
