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?

Well, the audiophile fuses I use are ISO certified to be used in any country. And they are not uber expensive like some other brands. 

In fact, I'm getting a parcel with some new ones hopefully by this weekend. They're made in Germany, sold in China, are gold plated silver fuses with 72 hrs of cryo treatment and 48 hrs of Quantum treatment and they go for a whopping $35 apiece. And they are ISO certified as well.

I'll let everyone know how I feel after trying them out.

All the best,

Please note I didn’t say he wasn’t a good guy. But he said he has no idea how these fancy fuses work. I’m not the one saying it, he is. So, how can he design a fuse? Doesn’t make sense. As I said previously, he should have just sprung for the HiFi Tuning fuses and be done with it. They were the ones that set him back on his heels, for crying out loud. They were the ones that he described as astonishing. He won’t do better than that. Hel-loo! By his own admisssion, unless he was keeping it under his vest, he doesn’t know why aftermarket fuses sound so good.

It’s not clear that circuit breakers are superior to the new wave of audiophile fuses, either. Although they are probably better than ordinary stock fuses.
Anybody who thought my post was "bullying" needs to go to their safe spot and nap for a while. I could post a "trigger warning" before writing things, but then I’d just feel like I’m pandering to the uber sensitive among us, and really, I’m just here to help people. (Not really, but saying I DON’T care seems harsh). Also, I'd like to see a discussion/debate between Paul McGowan and another amp manufacturer who disagrees with his position on Special Fuses.
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.
