I was only able to find two instances of the CC-50 for sale. One was in cherry. The other was in black, and bing.com showed that WholesaleAV had one (for $79 no less), but when you follow the link there's nothing and I don't see it anywhere on the WholesaleAV site.
The CC-50 is discontinued and might be difficult, if not impossible, to find new (outside of that one in cherry). Used might be your only option, or you might want to consider trying the newer CC-10. I dunno how well that'll match your existing speakers though, which I assume are the C-50s?
