I have to disagree with Pabelson on this one. Given my experience with Rotel (albeit, not that particualar model) I would choose the audio refinement even though it's older. I do agree that age doesn't play a role. In my opinion, the audio refinement will give more enjoyment, and have a better resale in the long run should you choose to upgrade.
Don't take our opinions though. listen and see which you like best if possible. Also, which speakers you are using will play a role. Rotel is a good match with B&W, but B&W is an even better match with the audio refinement.
