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?

Maybe fuse lovers should try the same fuses that the experts choose to use when designing their gear? Might save some $$$$s. Make sure the contacts are clean and the fuse is properly installed for best performance. Also of course always make sure the specifications are correct for use in your gear. You might not be able to afford top of the line VAC amps but you could probably squeeze the fuses they use.

>>>>>Huh? That’s kind of the whole point of this thread. Most high end amp manufacturers do not (rpt not) use aftermarket fuses. Nor are they even aware of them. Nor are they even aware of wire directionality. Nor are most audiophiles. Hel-loo! On the other hand, it’s a free country. You are free to ignore it, you are free to use aftermarket fuses, you are free to use circuit breakers, you are even free to bypass the fuses. You are even free to change the fuse direction or to not change it. I bypassed the fuse on my Super Modded Oppo. Was that wrong? 🙄

definition of an Expert: Some guy in a cheap suit 50 miles from home.

another definition of Expert: Someone who use to be a drip under pressure.

I Bypassed the Fuse in my Hot Rod Oppo and Lived to tell About it.
Newsflash. I can hear the difference fuses make. However, I made an extremely interesting discovery. What I discovered is that you must use them in matched pairs. Yes! I know some of you will be skeptical but it is the truth! Only matched pairs of fuses work. It maybe something to do with the positive and negative swings of the AC power. AC stands for Alternating Current. So it is made up of two directional movements. I have discovered like many that fuse direction makes a big difference. So I theorized that if fuse direction makes a difference then the best solution is to use TWO fuses in a matched pair. This discovery is probably the biggest discovery in audio since the tube was invented. A single fuse always sounds unbalanced - like the sound is louder from one speaker than the other - ONLY two balanced and carefully matched fuses will produce an even stereo soundfield and soundstage. Try it yourself. I totally guarentee you will hear a difference. Stick a fuse in one ear and listen then try matched fuses in both ears. Voila! No need to conduct blind listening tests - the difference is staggering - it is almost unbelievable but MATCHED pairs of fuses is the solution to achieving incredible soundstage and stereo image!
