The RS series was replaced by the RX series almost 2 years ago. Saturday Audio was a big player in selling the remaining stock but I think they're down to just the surrounds and center. Audiogon would be my best guess or just get some RX6's. The changes in the series were mostly cosmetic although I think they may have started using the GS series tweeter, not sure. I really enjoy my RS8's although if I had to point out a weakness I would say that the "sweet spot" is very defined when in stereo mode. Of course that's where my chair is located.
