I mentioned measurements of the fuses themselves. I have no doubt that Mike is hearing something and it would be good to know if the change is due to basic electrical performance parameters. It would also be good to be assured that specialty fuses will properly perform their "protective" duties. Imagine that measurements showed a distinct performance increase using the new fuse. Then, Dartzeel (and others) begin to spec those fuses for their electronics, etc. This is one pathway by which audio components have been improved: find a problem and solve it.
Beyond that, only Mike is intimately familiar with the sound of his system. Therefore, it would be logical that he would be the most likely candidate to pick up on small changes to the sound.
