Yeah, that is odd, although it might be buried in the manual. I was an early adopter of SACD. I bought a Sony DVP-S9000es back in 2000. It has RCA stereo output and both IEC 958 and optical S/PDIF outputs. Those, of course, carry CD, as well as 5.1 Dolby Digital; but, they do not carry SACD. The idea then and now is they (the record companies) don't want you and me digitally copying SACDs. HDMI outputs SACD since it complies with the SACD protocol, that's to say, you can't make a direct SACD digital recordings easily. At any rate, I just got an OPPO UDP-205 today, so now I can enjoy my multi-channel SACDs, as well as Stereo. I still do not have a pre/pro with HDMI input but the OPPO has multi-channel RCA output so I'm set.
