I've probably said this before, if you are not into classical music then don't bother with SACD as there is so little software.

If you are heavily into classical then there lots of good stuff available and plenty of new releases coming out.  Some of the best SACDs I've heard are 1950s and 1960s recordings rematered into DSD, the sound is just amazing.  One or two of the best sounding recording in my collection are early experimental stereo recordings made in 1954 - over fifty years old.  But a lot of good new recordings being made too.
