Lets look at all the available loudspeakers NEW and USED, at and below $10k and figure out what are keepers at the price and what could be bettered for less money? Totally selfish thread since i'm looking for a $10k speaker investment and want to narrow down the list of contenders. New focal Kanta, Dyna C60, revel F228 be. Used Salon 2, sopra 2, 207/2, Sasha 3, etc. Obviously speakers respond...
