I can't comment on the DAC in the CA, but the 8200AP is currently at the heart of my hi-fi/AV system, and it does a great job of movie and music soundtracks.
The M-DAC will be a simpler route, and may well sound slightly better, but the 8200AP also utilises bass management, which may be useful to those wishing to run smaller speakers with a sub, or indeed any speakers with a sub. I suppose the other added bonus is setting speaker distances and levels (even if only using two speakers). I sit a foot to the right of centre, and listen to a perfectly central image, mainly because of the ability to set the speaker distances from where I am sat. It is amazing the difference this can make.
