I have the Pioneer 578a DVD/CD player which plays SACDs. I also have the Harmon Kardon 135AVR. I have the six analog cables hooked up for SACD play. (as well as coax) What should the read out say on the 135? I put in a hybrid today and it read CD-Analog and it played the CD on both 8 speakers and 6 speakers. Then when I put in a pure SACD the display said 8 channel direct or 6 channel direct. I'm confused. What is the difference between the two? Are these the correct settings?
