I think it depends on what the system is. I bet if you looked at owners of the Wilson Wamm over 25% own the same gear. I Wamm, D’Agostino relentless, dCS Vivaldi stack.
Not sure there is anyone with the same system I have. That said my system is a bit lopsided right now where the front end is close to 4x the price of the speakers.
