Zenieth,
i owned EMM Labs for years (have had the CDSA in my system) and did own an AA Capitol Mk2 back 'in the day'. the EMM Labs is going to be higher performance and if your system has a natural balance i would recommend the CDSA. it is less forgiving and tolerant of any recording that might tend to be a bit hard sounding.....and as dgad mentions it is particularly good at SACD.
i don't want to get off topic; but i might recommend thinking about getting a digital player with hirez server DAC capabilities if you are going to be making a change. it's possible that the latest CDSA has this capability but if it does i'm not familiar with that.
