I got the Oremote app for my IPhone, thanks for that lead! It shows 44.1 kHz for SACD on DSD but it sounds better than a CD, so is this just a display issue? I am using the Oppo 103 via HDMI2 to the DHC 80.3, Audyssey off.
Exactly what SACD and CD tracks are you comparing to one another?
There might be differences in the recordings or in your listening environment besides the audio format.
I'm not claiming that the SACD tracks you're listening to aren't better than the corresponding CD audio, but it would be interesting to understand why you're hearing those differences.
Often more effort is expended when a mix is known to be destined for one of the high-definition formats. Also, older CD production systems did not have the benefit of the high-quality digital processing which is the norm now. Still, too often modern CD audio tracks have been damaged by compression in amplitude. It's too bad that there isn't a standard reference for music recording like there is for movie sound tracks.
In addition, don't forget that when there are slight differences in volume level, the one which is ever-so-slightly louder sounds better. Since the paths through the electronics are different for PCM and DSD, it's hard to ensure the resulting sound levels are identical.
And, of course, one should try to avoid "expectation bias". Often a system which is known to be higher quality sounds better, whether or not there's actually any measurable difference.
