I've found that most decent speakers sound... well... decent. There are some speakers that have a specific sound or nuance to them that you either like or dislike. Kipsh is one of those for me. There's just something about that big horn that makes the tones sound harsh. Infinity and Martin Logan are two others that come to mind that just have more of a signature style sound. Gimme Def Techs, Axiom, B&W, M&K, Dynaudio, and a host of others and I doubt i'd throw any of them out of bed.
