I'll respond to 2 comments here. I have all the Doors SACD's , never realized till I looked they are multi channel because I like music in 2 channel stereo. The Denon DCD-A110 SACD player I bought 2 years ago is only 2 channel because it depicts realism. Like a concert experience. I have a 9.2 dolby atmos surround system for movies , sports , etc. So the Doors SACD's have actually 3 layers. Top is redbook , first imbedded layer is 2 ch SACD , second imbedded layer is multi channel SACD. The original SACD's which are mostly from 1999=2003 were one layer only and will not play on a conventional cd player. To me they had the best sound. You can find them used and they are quite expensive.
I still have a Denon 5900 player that plays the old single layer SACD's fine but will not play the imbedded SACD layer on the hybrid's. Had a new laser installed and same problem. I went thru 5 Sony DVP-S9000ES players and never found any that will play the hybrid SACD layer either. These players were all mfg before the hybrid SACD's came out and since the player mfg could hardly anticipate their arrival , my opinion is the old units will not play the hybrid's because they were not designed for them. If you like the 2 channel sound , I'd recommend grabbing a used Denon DCD-A110 SACD player , saw a couple for around $2,300. They weigh 35 pounds and are built like a tank.
