Better late than never - for those doing research for current day purchases:
I've owned many of the digital systems mentioned within the various responses. Additionally, I have owned Pass Labs amps (Alephs + a 150.5) and have owned Wilson speakers (Cub, W/P 3/2, W/P 5.1, Duettes).
DCS into the amp and into the Wilson speakers is very, very good. I have to assume that since you own Wilson speakers you want a detailed, forward sound (even though the Sofia are a bit less forward than the W/P).
The AA Capitole and will seduce you, it is beautiful, full, bloomy, bloated in the bass by comparison, very, very warm sounding and lacks some detail as a result. This is typically a CDP that is contrary to what many Wilson owners are looking for. It is a great additional CDP, but this warmth may wear/bore on you over time. Also, you may want to buy two for when it will inevitably be in the shop for repairs - in France were they work very sloooooowly. I have one in the closet that needs to be serviced for the second time now. Replaced the entire Stars system and tubes the first time.
The RA 21 is only special with the GNSC mods, then it is quite good for the used price, but in a different league vs. the DCS, EMM Labs or AA units.
If you want detail then I would add Esoteric and Wadia for the forward sounding wants.
For the neutral minded, I would include EMM and DCS and possibly (but at a noticeable step down) the RA 21 GNSC'd.
For warmth I would include the AA (probably two units to be safe) or better yet, the AMR units. I would tend to skip the BAT or Cary in this category as vs. the AA and AMR you get a more stereotypical tube warmth with a much more notable loss of definition.
This is all just in my opinion. I have owned every brand/model referenced except the BAT and Cary which I have auditioned several times.
