Has anyone made the jump to $uper High end and were disappointed?

I'm talking $50,000 and higher amps, speakers, cablesetc. I know there is excellent sounding gear from $100 to infinity (much is system dependent, room, etc). However, just curious if someone made the leap and deep down realize the "expected" sound quality jump was not as much as the price jump. Unfortunately, I'm not in a position to make that jump. However, looking at another forum's thread about price point of diminishing returns got me wondering if anyone had buyers remorse. It's not easy to just "flip" a super high priced component.
