I amend my previous post. I played the Channel Classics recording of Mahler's 2nd Symphony and the Hamonia Mundi recording of Biber's Missa Christi Resurgentis, both of which are in DSD surround, but can be switched in my pre/pro to stereo. The audio was excellent, and the surround very effective, especially for the Biber choral work, capturing the spacious feeling of the cathedral even better than the stereo version. The onscreen is informative, with a restful wave pattern generated by the PS3-80 as a background. I will no longer be ignoring the PS3-80 as an SACD players.
