I know golfers that own dozens of putters and they're all in the back of one of their closets.
Sometimes people just aren't patient or smart enough to know where the source of a problem is. With a golfer it could be his swing or alignment that is causing the problems.
With an audiophile, maybe his room sucks the life out of any component he puts in it, yet he continues to hope that the next, best component will fix his problems.
