Yes. I would have to be a fool to spend that much on a fuse. I would be an even bigger fool if, after spending more than $2800 on such a fuse, I convinced myself that just by changing that fuse my soundstage opened up, backgrounds became blacker, and that my system sounded night and day better because of that fuse. The only way that would be possible is if the fuse I replaced was significantly damaged or worn out from being very old. But then again, I would have tried a factory replacement fuse as my first option regardless. Products like this, IN MY OPINION, take serious advantage of people by making unverifiable grandiose claims. Now, let the post deleting and censuring begin!
