Your credentials are admirable, but I too have worked in the audio industry for over 30 years. I've been through the gamut of tweaks that did nothing (Armor-All on CD's, "Magic Pebbles," etc.) and have found many of them to be simply ridiculous. "Ridiculous" is also an apt word to describe the high prices of some interconnects ($3,800 for 1/2 meter cable?), and paying thousands of dollars for something like a record clamp borders on the insane. Still, these fuses - at an admittedly very high price for a fuse - at least to my ears, my wife's ears, and those of a good friend - were worth the expense.

The only way to eliminate you skepticism is for you to try them yourself, but I guess that's not very likely. Oh well,.....
