I would like to see these fuse builders identify their own fuse, in their own system, in comparison to the stock fuses, or competition too. They could be changed by a qualified neutral party, without their knowledge of which one their listening to. This would be a simple fair test, that would probably satisfy a lot of people, besides me. This would be interesting.
If you are suggesting blind listening test, then none of the other audio tweaks mentioned will pass the test either.
