I've got Kind Of Blue on SACD. I purchased it in 2000. It's labeled STEREO/Multi-Channel SACD and it is. Until I bought an OPPO UDP-205 Universal Player in Feb. of 2018 I could only enjoy the SACD in stereo from my Sony DVP-S9000ES. Now, I get 5.1 and stereo from the OPPO. The OPPO plays out to my Sony TA-P9000ES 5.1 analog multi-channel preamplifier. Reading your post, I thought I would check again for multi-channel output; and, sure enough, I've got front left/right, center, rear left/right and subwoofer action. Maybe you have a bad SACD, or your player/amplification needs to be adjusted to permit 5.1? At any rate, I can play my SACDs, stereo or multi-channel from the OPPO via direct DSD to analog or DSD to PCM to analog. If I go the DSD to PCM route, the OPPO manages 5.1 channel crossovers and volume from each speaker. With current settings, where all channels are volume matched, there's not much sound coming from the rear speakers on Kind Of Blue. There's just enough to present a sound stage which has more breadth and depth than the stereo version of Kind Of Blue. BTW, earlier today I played a Diana Krall multi-channel SACD where rear channels as well as subwoofer are more aggressive, still the sound stage is set much like I've seen it from a Diana Krall BD.
