FWIW, based on my use of a Marantz SA11S3 and from what I've read about the Cary, if I had to make a blind choice between the two I'd base my decision on the tonal balance differences between the two. I'd guess that I'd prefer the Marantz in a leaner system(SS?) and the Cary in a warmer system (tubes?). I find in my system (definitely warmer) the Marantz sounds best with small groups and solo instruments. The lower mid-range upper bass seems to get a bit thick (compared to my Wadia 302 which I much prefer on large orchestral music in general, especially those with a warmer balance in the first place). I'm agnostic about SACD's - as far as I'm concerned the performance issues involved in most recordings will overwhelm any sonic benefits of redbook v SACD.
Hope that helps, a little bit anyway.
