I've got two Sony BDP's (S 580 & S 390) and I love 'em both, but I might be a bit biased here. Anyhow, I BELIEVE it plays SACD through the HDMI output, not in an analog output format like the Oppo does. Again, I don't do FLAC.
I have a separate (almost - no BD) universal player (Denon 1940CI) for my SACD needs.
