What I have found with my Oppo 203 & Pioneer SC-LX86 is that when a SACD has been authored 'hot', i.e. at or above the SACD level spec either will cut-out the audio when it hits that hot level. But they don't both do it with the same disc, so its down to their conversion algorithm! For example my AF Bob Dylan "Live 1964" SACD would cut-out the audio if I let the Pioneer play the DSD, but the Oppo happily converted to PCM with no audio cut-out - I can't remember which disc was the opposite. So, I usually let the Oppo convert from DSD to PCM until it objects to it, otherwise I can't tell the difference in the audio quality.
