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?

I didn’t realize the military had so many audiophiles. 😬 Are the highest level fuses directional? Do they have military grade fuse holders, too? I will say I have tried and like very much the MIL SPEC Silver on copper Teflon wire from US Navy surplus. I also used to have power cord from US aircraft communications section. Someone needs to reverse engineer the military fuses obviously. On a sour note, this fuse thing sounds suspiciously like the old Hospital grade wall outlet fiasco. And Hospital grade power cord plug. They’re good, but not as good as audiophile grade wall outlets and plugs. The plugs are designed primarily not to pull out of the socket easily. The audiophile grade outlets *sound* better, and they also have great mechanical contact. Having written specifications for military communications equipment I’d opine the chances are good the MIL SPEC for fuses specifies reliability and shock resistance, things of that nature, but not sound quality. But Mil Spec tubes sound great! Final answer.

@geoffkait , I agree with your assumptions regarding fuses and their intended uses, which originally didn't include audio. I think it was just a matter of time before some forward thinking audiophiles took a good, hard look at what's out there and capitalized on it. 

Good for them. I wish I'd done it. 😖

It will forever be argued that the markup is too high but some these fuses and are seeming to be purpose built for audio applications while some are just rebranding. They're not all alike and some perform better than others so it's threads like this that help to sort things out.

All the best,

From a quick scan of military fuses it appears anyone can buy them from at least two sources, our old friends Littelfuse and Bussmann. I think the problem for audiophiles - aside from the obvious one, what they sound like - is that they are apparently all super fast blow fuses. If I’m not mistaken almost all aftermarket audiophile fuses are slow blow.

Costco, I see no reason for you to refer to me as God. Explosion proof? Maybe, but audiophile outlets and power cord plugs are still better sounding than hospital ones anyway. Just like audiophile fuses are better sounding than military ones. So who cares?

Have a nice hair day
