How do the Cubs sound compared with the Cub2s?

I have listened to the Wilson Cubs and liked them and am considering buying either the Cubs or the Cub2s. I have heard that the Cubs are bright even though at the dealer they didn't sound bright to me and wonder whether the
Cub2s are less bright. I have a Tact preamp and plan to upgrade my Phase Linear 400 power amp in the future to a Music Fidelity or Tact digital amp but would welcom suggestions.
