Hi Ryan. Yup, I use my Oppo for SACDs. And honestly, for my modest means, it sounds great. Certainly better than my old Pioneer 588a, without a doubt.
The Oppo handles SACDs flawlessly in the audio department. The only thing I don't like is extremely minor: I can't get it to switch between time elapsed to anything else. It shows me time elapsed for the currently playing track, but not track time remaining, disc time elapsed, nor disc time remaining. Like I said, it's a very minor quibble. Everything else about SACD playback on the Oppo 981 is stellar.
I'm using the analog outs for hi-res playback, not the HDMI, so I can't comment as to how the HDMI 1.1 handles SACD. But I'm very, very happy with the SACD playback.
cheers,
