I have Synergistic Research Orange fuses throughout my system. Before that it was Blue. Both are so clearly directional, and better than Buss, that I have to believe anyone unable to hear this should seriously consider another hobby. Can't speak for any others, haven't tried Hi-Fi Tuning, but Blue and Orange are very good value for money.
Except for the ones inside my Verus turntable motor controller. There's two in there and the improvement is so slight I would have sent them back, were it not for the fact they were freebies included when buying something else.
So imagine, a guy who can hear directionality, hear fuses, and is even able to evaluate their relative performance in different components. Why make up a story like that? I'm sure the deniers will come up with something.
