Finding a DAC that will process SACD's

I have a Oppo 981 that plays SACD's too. I definitely want to add a D/A converter to improve on my CD player. The Benchmark and PS Audio units have been recommended in my price range. But I want to make sure they will process my few SACD's. What do I look for in a DAC to know if it does. Any recommendations ? Need a little help in trying to educate myself on the higher end gear.
