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?

Those measurements clear it up for everyone?  I love to listen to measurements.  The warmth of some measurements versus the clinical sound of others.  Oh the humanity!
Entertaining reading guys!  Lots of snarky repartee.  Both Kosst and Geoff might want to watch "Morning Joe" on MSNBC with the sound off.  You've never seen snarky until you've watched Mika Brzezinski's face and the impact of her visual condescension.  Have fun!

Kosst - Do you really believe that all the subjective descriptors mentioned in Geoff's earlier post are quantifiable with measurable data??
@wolf_garcia   Why?  Why the name calling and middle school responses?  Did you see the video of that poor middle school boy who was being relentlessly bullied at school?  Come on...you're better than that!
@kosst_amojan   ??? Re-read my posts?  Maybe I'm just being obtuse this evening.
An observation.  Paul's video experience with hearing a difference when fuses were changed in a component he designed when he had no idea what adjustments were being made to the component directly goes against the oft referenced phrase used here as "Confirmation Bias".  When it was revealed that the change made was the substitution of fuses, he was astonished!
@geoffkait  If I remember correctly, I believe Paul indicated that no matter what fuse he incorporates into his designs, there will be audiophiles who will replace them with their own more exotic parts. He already pays attention to the impact that fuses/circuit breakers have in his various designs.  

One thing that Paul does that I admire is, whenever possible, Not promoting PS products in his videos.  He Does include interesting anecdotes in answering questions from his long-time involvement in audio design.  A good guy.
I did have a conversation about fuses with another well known amplifier designer, Steve McCormack, when I need to replace fuses in my modified DNA-1 Deluxe. The fuses blew because of a stupid mistake on my part not on any deficiency with the amp. Steve had a clear preference for HiFi Tuning Silver Star fuses which at the time of the conversation were being sold at a discount due to being replaced in the HiFi Tuning line by the Supreme fuse. Steve mentioned that he tried the Supremes in his gear but preferred the Silver Stars.
@nonoise  I could be mistaken but I believe the argument made by fuse skeptics has been that merely the process of removing one fuse and inserting another is, through the friction involved in that action, removing oxidation from the fuse holder giving the reinserted fuse a cleaner connection to the holder and thus a perceived improvement in sound.
Exactly nonoise!  My experiences with Steve McCormack have always been based on what is heard not a belief, myth or fable. He engineers a solid design and chooses each capacitor, resistor, wire, etc. to maximize the sonic performance of his gear. I wouldn't want to own components from designers that would do otherwise.  

My guess is that a great number of equipment designers take wires, fuses, directionality etc. into account.  As Paul McGowan said on that video, He's an audiophile too!
@nonoise Totally agree with point #1 above! We are serious listeners who truly care about what we hear, not whether or not we can provide experimental data to validate what our own ears tell us.

As I have mentioned before...if someone doesn’t hear an effect that we perceive that’s fine. We recognize that as individuals we all will hear slightly differently due to anatomical differences and/or the interface between our ears and our brain.

Agree with #2 above with the caveat that I think the argument isn’t about the amount of surface contact, but that rotating the fuse will displace oxidation or dust/dirt to yield a better electrical contact. Oh, and yes, as you stated, rotating fuses in most holders is a B****.

@mrdecibel   Regarding the first of the above two consecutive posts, no noise and I have been expressing a similar sentiment here. ( I hope I am accurately portraying your sentiments here, nonoise) The point you rightly emphasize is about the naysayers who haven't even tried the very tweaks they disparage.  I'm not going to categorically state anything as absolute truth in my experience, if I haven't experienced it!
@kosst_amojan   We are not seeking proof.  We are not tweaking the sound of our systems so we have something to measure.  All we care about is maximizing the sonic satisfaction we receive from our systems.

It is not about facts.  If I change footers under my preamp and I enjoy the sound more, if a guitar sounds more like a real guitar is in the room, for example, then that's a change I will embrace.

I'm not going to measure it or even try.  What in the world would you measure such a sonic change with?

I appreciate science and solid engineering principles as much as the next audiophile but it is not a religion for me.  It is what allows well  designed gear to exist but it doesn't inform my entire listening experience.

If tweaking footers, tubes, wires, fuses etc. isn't an aspect of the audiophile experience that you want to participate in, that's okay.

Enjoy the music!
@mrdecibel   Very well said, sir.  I think you, in these last few posts really captured the kosst syndrome.🤔
Paul McGowan is very transparent about the power cord issue.  He, like the vast majority of audio entrepreneurs, brings gear to market at a specific price point.  He includes a good, heavy gauge power cord with his regenerators but notes that upgrading from that cable can improve the performance of his gear.  Additionally, Paul endorses his customers to use resonance/vibration control devices with his regenerators and other gear to further enhance performance
