and that now sounds like a troll message. Anyways....if you feel that we are the religious zealots, that is interesting because we are only responding to your "attacks" saying that we are completely wrong in our objectivity and results -- where you have not even listened to an upgrade fuse.
1" of A/C circuit is important, especially when the conductor is going to be a really thin wire somewhere between 20awg and 26awg that is typically non-damped and tensioned in air (which will have electrical mechanical resonance just like a guitar string would when plucked).
I can even tell differences when using the larger 10 amp type fuses with the thicker/higher awg conductors. I just recently went through an exercise comparing big 10A fuses in a receiver (Hi-Fi Tuning Silverstar, Hi-Fi Tuning Supreme, Furutech, stock). All the 10A fuses still had different sonic signatures. The differences were drastic enough where it sounded like completely different amplifiers.
There are definitely other areas which affect sound, like power cord connectors. If you look at a standard IEC connector, there really is only about 1" of conductor as well, but there is an audible difference between an IEC connector with gold-plated conductors and silver or rhodium plated conductors.
Same thing occurs with RCA connectors (another element that is less than 1" long!). There is a definite audible difference between an gold-plated copper RCA plug and a solid pure silver RCA plug.
