I think the 60 and 80GB versions of the PS3 support SACD while the 40GB along with the 20GB are the stripped down versions. I'm trying to understand your situation, do you want a dedicated CD/SACD even dvd-A player or you're not quite sure which version of the PS3 to get? Depending on your set-up and budget of course, there are plenty of excellent univesal players out there that'll do the job.
