OK, let’s get this thread back on track, people. Which is why high end amp manufacturers don’t employ audiophile grade fuses in their amps. The obvious reason is they aren’t aware of aftermarket fuses or ANY issues with fuses, including wire directionality, so why would they? It’s an audiophile thang. And even many audiophiles don’t subscribe to high end fuses, so why would amp manufacturers? Hel-loo? As I’ve opined before, amp manufactures are, generally speaking, obsessively “circuit oriented” and very conservative when it comes to audiophile concepts like fuses, or power cords or vibration control. Another possible reason high end amp manufacturers don’t use high end fuses is they don’t have the inclination or time to keep up with all the developments in audiophile fuses, even if they were aware of them - which they’re not. There is a new development in fuse technology about what, once a year? Plus the manufacturers would have to ascertain the correct fuse direction. That would be the minimum, and they don’t even do that for whatever stock fuse they use. So, most likely they are blissfully unaware.
Furthermore, if an amp manufacturer IS cognizant of aftermarket fuses, which he’s probably NOT, he SHOULD be aware of WHY the fuse is IMPORTANT, even CRITICAL, to the sound. Consequently, the minimum effort for an amp manufacturer should be to implement vibration control, RFI/EMI control, magnetic field control to the fuses as a matter of course.
“We don’t need tweaks.” - German high end amp manufacturer at CES circa 2000.
