So I went ahead with the LSR305+310S. They sound awesome! I didn't realize it could get this much better than the Klipsch. But I have 2 minor complaints: there's a quiet white noise when no sound is played, even with the XLR cable unplugged, and even when playing complete silence (unless the volume knob is 0-1). Secondly, moving my mouse causes an interference sound...running a desktop with an Audigy 2 ZS. I guess it might be related to voltage noise due to waking up the CPU, because it doesn't happen if I'm running a CPU stress test at the same time. So I'm thinking about gettin one of these.
