Thanks gosta. I actually ended up getting a Thiel SS2 and an Integrator. It transformed the entire system to levels that I never even thought was possible. Ironically, the biggest different was actually in the midrange and high end of the speakers... another level of purity and smoothness that I didn't think the CS2.4's could do.
The bass with the SS2 is a real marvel. So incredibly fast and well integrated that you never know if it's on or not (unless you shut it off, then it's obvious).
