That’s a massive assumption of yours, I have had an owner of one of these $150+ fuses who swears by them, he bought one to my place I "pretended" to put it in, but I DIDN’T. Then played the system again, he said wow that’s better!!!!
These people who say it does not make a difference are not willing to experiment.
Then I put it in, he thinking the old Bussman went back in, then he said that’s back to being worse.!!!!!
I didn’t have the heart to tell him, he was conned. As he is a customer of mine.
BTW I heard absolutely no difference compared to my $2 Bussman fuse.
