I had Thiel CS3.6's and then CS5i's and could never get a good soundstage and dynamics.
Currently running Klipsch Forte iv's and Zu Audio Soul Sixes, both of which sound more live and dynamic to me.
It is nice to not have to deal with heavy, high current, and high power amps. Currently using a First Watt F7 or CJ LP66s, depending on my mood.
