Billy, I haven't heard any Martin Logans, but like any speaker choice--let your ears decide for you. Listen to them as much as you can with different types of music. What sort of things do you find desireable in a speaker? Image and soundstage? Warm midrange? Smooth treble? Detail? Emotion? There is no answer I can give you. It's a process. Don't be afraid to like something, and more importantly, don't be afraid to dislike something--no matter how much money you spend. The goal is to find something you are happy with.
