dac or sacd?

You can also get a CD/SACD player with digital inputs that will allow you to access the unit's DAC to use with a PC or music server.

*none* of the music I listen to is widely available on SACD. I've looked. So before diving in, do some research and see what's out there.

Here's the research:

Pop/Rock: 546 titles (http://www.sa-cd.net/titles/3/0/date/5/1)
Jazz: 1127 titles (http://www.sa-cd.net/titles/2/0/date/5/1)
Blues: 77 titles (http://www.sa-cd.net/titles/9/0/date/5/1)
Classical: 4443 titles (http://www.sa-cd.net/titles/1/0/date/5/1)
All Genres: 7212 titles (http://www.sa-cd.net/titles/0/0/date/5/1)

Not exactly a dearth of options outside of the Classical realm but certainly Classical is just over 60% of the titles. The sa-cs.net site is the definitive resource for those interested in SACDs and for each title listed provides link(s) to vendors where you can purchase that title. Enjoy.
