Now explain why every time my audiophile buddies over the years have claimed some amazing improvements from fuses, when I forced them to listen blind, those amazing improvements disappear. I do make sure to clean the fuse contact first to remove that variable.
Yes, confirmation bias is a thing and it’s proven every time someone says fuses can’t, and won’t, make a difference. They believe it so deeply that when they listen, they don’t hear any differences or write off any as of no consequence.
