Your single most significant purchase mistake?

Your most significant regret for having bought? Big expectations and an even bigger letdown? The one you kicked yourself the hardest for ever having bight 


this is a fun informative thread

there are numerous items listed by others, highly respected, experienced users, that i have tried myself in the past and actually liked a lot... while i moved on, these items certainly would not be on my ’top worst mistakes’ list

big thiels, muse amp, vac pa 100 (i had/still have the 4 chassis 90-c’s), nht 3/3's... of course every component, at any level of quality and cost, has strengths and weaknesses, but i think this just shows how varying personal tastes can be, how different specific use cases/applications are, how important synergy is in systems with mating components... fascinating stuff...
