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?
