Your single most significant purchase mistake?

Weaver likes 6 figure everything, has a head twitch, and a martini issue. I try very hard to avoid his over the top bombastic pomposity. He uses the same 100 adjectives over and over...I tired of him after the first 10 episodes.  Perhaps that is the time waster I regret most..lol.

2 examples come to mind...a trapezoidal shaped Kenwood receiver with a space age LED pad remote that had a shape to match.  Oh and also the Kenwood that came with the blue smooth membrane remote, Kenwood tried hard after the classic silver-face days to bring innovative space age looking designs.  The products just weren't ready for prime time.

And even worse, and some years earlier---a "home theater" set of Pinnacle speakers bought at hi-fi-fo-fum in Lawton, OK.  The subwoofer even was passive.  Only speakers I ever had that had a zero excitement to its sound signature.

Oh sorry it was supposed to be singular---I don't like abiding by rules. If I were pressed---the Pinnacles.
