If you don't care about SACD, put the Audiolab 8200cdq on your list as well. Several digital filters which allow you to adjust to your liking. You can read review on 6 Moons. I also own the Rotel RCD1520 but this Audiolab is much more feature rich. I'm not saying the Rotel is not good, but you have so many choices as to how the Audiolab sounds that you're bound to be able to tweak to your liking.
