Chinese "Audiophile" Fuses


I have recently had various Chinese "audiophile" fuses pop up in my newsfeed. One of the oddest ones claims to reduce resonance by filing the middle part of the fuse with nanographene and the end caps with powdered quartz.. This strikes me as a crazy concept because graphene is an extremely conductive material. How would a fuse that surrounded the wire in the fuse with graphene possibly work? The wire blows but the current still flows though the graphene and my amp self-destructs? WTF

Fuses are made of conductive material. that said, I wouldn't trust these to blow at the designated current.  I've often thought one of the reasons audiophile fuses sound better is because they are at the top end of the tolerance.  

Frankly, I doubt there is much if any graphene used.

and nobody ever tests what current they blow at since they are so expensive.

I don't think the fuse blowing protection is the purpose of those fuses.

Probably sound quality is the goal. In which case just adding a slug instead of a fuse would suffice. That is why I use the SDFB it provides the slug (graphene) and breaker protection.

@ozzy Have you compared the fuse against using only the slug? Does the addition of the SDFB improve the sound? Or is it only for protection?

noromance,

Funny you asked this question. Yesterday, I did run my AQ Dragon power cord directly without the SDFB. Just the graphene slug installed.

Now to me, it seemed to be better. But I think it is because I am using an inferior jumper pc in the chain. The AQ Dragon power cord is a fantastic pc in its own right.

I do wish Mark would change the design of the Fuse box to an IEC male on one end so it could be inserted directly into the component, or the other end to have an AC Blade male to plug directly into the wall without having to use a jumper pc.
