My biggest mistake was not anticipating how much fun this hobby would be and so started out not spending what I could have and therefore continually upgrading. For example, I went from a Rega P6, then an 8, then a 10, and then scrapping the brand altogether and bought a Bergmann table. Same with the phonostage- went through 3 before getting what I ultimately have kept. Same with my preamp/amp - started with an integrated and went to separates pretty quickly after that. Each time losing some money all the way and let me tel you it adds up!!!!
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
