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?

Because they know better and are technicians, who build their amps using all the laws of electronics. If you ever find one that doesn’t, that can’t prove why they don’t, steer well clear of his products.
But some may throw these boutique fuses in as bait for a sale. But I guarantee they won’t put in writing the technical reason why it’s there.

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.

what can you possibly "expect" from a $25 fuse in a $60K system that already sounds great.

That's just it, "expectation bias" will ring forth after spending $$$ on a 10c fuse.

Which is why high end amp manufacturers don’t employ audiophile grade fuses in their amps.

Of course they would if it made the amp sound better. Better sound = more sales!!  But sadly Geoff it doesn't.

What’s sad is they, like you, are ignorant of fuses. Obviously. Obsessively circuit oriented. It doesn’t take a weather man to know which way the wind blows. Wake up and smell the coffee!

Ooo, getting testy there Geoff, your calling the most influential designers in audio "Ignorant", I don't think it's them, but I'm sure they'd have something to say about you.
