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?

Huh? It’s basic economics. Obviously manufactures don’t want to keep product on the shelf. This is especially true in hard times like uh, now. Especially for esoteric and exotic products, like audiophile fuses, who knows what the lifetime is for many esoteric products? A year? A month? What every small manufacturer wants, hopes for, is a BIG ORDER. If Isoclean received a big order they would find a way to meet it, no doubt about it. It would be worked out in advance. If SR got a BIG ORDER they would find a way to meet it. It wouldn’t happen overnight, obviously. It’s called planning. Plan for the future! Taking the easy way out is not really the best course of action. That's so Mid Fi. Strategic planning is the only way to go for High End results.

What do I use in my Pass F5 clone? Bussmann. They sell them in 6 packs at AutoZone. They work great. They blow very consistently if I fumble with the power switch wrong. $50 for a fuse? I don’t think so!

Good for you! What direction do you put them in? Just curious. Maybe one day you'll be able to afford a real Pass F5. Fingers krosst.
For the manufacturer, its all about keeping the cost down and having a competative price. $$$$$$
You have my absolute guarantee I can make fancy fuses faster than a high end manufacturer can crank out amplifiers.

I put them in the long way. It's the only way they fit. Nelson seemed to like my amp. He called me a "fearless amp builder" for my going with 34.5V rails and removing the current limiting. In fact, my build is a full 50% more powerful than the First Watt version. Why would I try to hunt down a very rare amp when I can build as many as I want any way I please?
