I've listened to all the above mentioned speakers and there are some very good monitors listed, but for me, the Green Mountain Audio Callistos took the prize. First order crossover's do not color the vocals or the music. Pure clean sound that has brought me closer to the music than any other speaker I have owned in the last 30 years. Demo several and find out what sounds best to you.
