I’d be curious if one disguised and regular old 10 cent fuse as a $2800 one ( if it were possible to disguise) and conducted a comparison to the same model fuse undisguised, would people ( thinking the disguised fuse was real) still pick the disguised $2800 fuse. 

Paying thousands of dollars for a fuse is pure insanity, regardless of whether they make a sonic difference or not.  However, if they contain quantum tunneled dark matter and antimuon alloy, then it's totally worth it.

I recently disguised all my fuses and put directional arrows on them and the sound of my system has now been totally transformed!
