LittelFuses Series 285 AUDIO/MEDICAL Quality

George,

They are ceramic, but the point is they are designed for audio and medical applications.  I was looking to see if anyone used them and if so there experience vs "audiophile" fuses.  I believe audiophile fuses my have better sound, but I am not willing to sacrifice my equipment on fuses without industry standards.   Like bee's wax fuses - come on!

In the link I provided the users reported hearing a difference between a standard fuse, the gold capped, and the rhodium capped Littelfuse. 
Also noted was the PADIS fuse which uses copper.

Yes, Thank you for that link. 

I have Audio Research gear and once asked them why they didn’t use audio-grade fuses. Their response was simple in that they could not hear a difference between the standard Buss fuse (they use) and the expensive “audio” fuses.

Without going into the whole fuse thing, replacing a fast blow fuse with a slow blow is not a good idea.
