If you like Thiel speakers try to find used CS6s. It might be difficult to find something better even if you pay 10 times more. CS 3.7s have nice midrange but the base is incompatible with CS6s which are truly coherent speakers with very good coaxiales.
Best 40 to 50k used speakers
What would you consider the absolute best speakers on the used market, budget 40 to 50k max.Open to any suggestions thanks.
