Which SR Blue or black Fuse

Remove all the screws from your gear, and replace them with titanium versions. Your gear will sound that same, but it will be slightly lighter, possibly resulting in the .0000023% sonic improvement attributed to fuse direction. I did say "possibly" but sonic enhancement from a fuse is mythological at best, and expensive at worst.

I thought my natural body oil WAS a contact enhancer, which has kept me from showering during Contact Cleaning Week. 

I'm not happy about the results I reported about the Magic Fuses I tested as I know it saddens many who shelled out their tweak bucks for the things, and causes them to try harder to "believe" their fuses do things fuses don't, can't, and never will actually do...I get that...I simply say soldier on people...your gonna be OK! Now if I could just arrange that tour of the Littelfuse factory...yeah man...maybe meet Mister Littelfuse in person! I can be an "insider"...

The only fuses I've used in recent years that blew were SR Black fuses I was testing for their sound. Also, I concluded that they had no impact on the sound of the components I stuck 'em in, and after testing I sent the pile of them back to my source. I'm sticking to Littelfuse and other stock fuses that work fine and, like any other well sorted fuse, have zero impact on the sound except when they melt.
