Russell, I am not sure how the layers are played, if different layers are read at all. My SACD, I thought, only reads two layers since it is not a multi-channel player. Just plays SACDs in stereo. When the box arrived it occurred to me that my player might not be able to access all the tracks on the CDs, missing the tracks on the multi-channel layer. I was already to send the box back unopened, but decided to go ahead and try a disc, and found out the player played all the tracks straight through with no interuption between layers. I actually don't know what's going on. The box just says you need a SACD player, no mention of needing one capable of three or four, or five, channel playback. My player offers a choice of which layer you want to listen to, the CD layer or the SACD layer. I figured I'd have to listen to one layer, and then press the button to switch to the other layer. No such thing. Someone more technical than me, might be able to figure out what's going on.
