The DV-45A can be setup to default to the 2 channel SACD area only. ALL SACD have a stereo area. The stereo 2 channel RCA's and the front left/right multi-channel RCA's are parallel pairs, ie. exactly the same, coming from the same DAC. It's the mode setting of the player that determines the output as multichannel or stereo, provided the disc has multichannel on it. The amount and mix of the two formats varies, but the player can be forced to do either. And if the disc has not the information you want, it will default to what's available, ie. if you select 5.1 and the disc is not a multichannel it will still play the 2 channel. I don't have any information on the DVD-A setup yet, still waiting for some good discs to show up...
