Glenalan:
My CS-2's play very well at low volume. My Significant Other (SO) watches the TV and listens to the Tuner through the system at low levels and loves them.
I refer to their sound as clean. No coloration that I can hear, and you can easily judge the quality of the source components through the speakers. Bad recordings or an inferior source will easily be identified. They hide nothing.
Further, small sounds (water lapping against the rowboat in The Pirates of the Caribbean) that got "lost" before, now are easily heard and add greatly to the experience.
