Anyone used these audio ceramic slow blow fuses from Littlefuse?

Littlefuse and Bussman have always made ceramic fuses. It would be interesting to compare the specs and test results to these new ceramics. It's worth $9.00 to compare the gold/ rhodium-plated vs. the standard ceramic fuse.

I do hear a sonic difference when using audiophile fuses, some more than others. But to hear a worthwhile improvement does cost more.

Yes, Littlefuse has always made ceramic fuses but up to this point their offerings have cost a dollar or so at the most. The economy of scale that they potentially have in manufacturing does make one curious as to how these compare to standard issue fuses and the $50-$200 varieties. Fuses are simple things. Other than the wire elements, the material that caps are made from, and any possible filler, there's not much that can differ between brands. If no one chimes in with actual user experience, I'll have to spring for some myself to test in my PSA BHK preamp and amp.

“Fuses are simple things.”

They look simple, anyway. 🤗 What do audiophiles know that Littelfuse doesn’t? 

At the very least we know Littelfuss will spec accurately and have excellent quality control. They have an enormous and sophisticated customer base in. Ritical industries. I’ll buy and try when the opportunity arises. 

In reality, Littelfuse fuses blow prematurely just as much as fancy audiophile fuses. Nice try, anyway. No industry is more ritical than audio. Didn’t you know that? I assume you don’t know any audiophiles.
