I do not think there ever be any multi-channel SACD movies, or DVD-Audio movies. Movies are either in DPL, DD, or DTS.
SACD, which stands for Super Audio CD, is for music, and is intended to be a better CD. You can play dual-layer SACDS in your car CD player.
Right now, 99.9999 percent of CDs are stereo and not 5.1. Do you recommend everyone to wait until we have 5.1 CDs before buying another CD player?
By the way, DVD-Audio is 5.1, and the one's I've used have not supported stereo (Doors and Nevelle). SACD supports both stereo and 5.1.
David Chesky, of Chesky records, in creating multi-channel SACD discs, concluded that 5.1 is NOT the way to go with music. He found it impossible to get clear imaging between 3 front speakers. Therefore, his SACD multi-channel discs will not use the center front channel. He's also not using the sub-woofer, so his discs will mainly be 4 channel. He will send a signal to the other two channels, but he assumes that the speaker placement will be in the back of the room (2 speakers front, two on the side, and two in the back) if someone wishes to use all 6 channels.
Back to the question at hand. I own an S9000ES. With it I can play some of the best quality 5.1 DD, 5.1 DTS, and 5.1 THX movie sound by using the S9000ES digital outs to my Rotel pre/processor. It's vastly superior to my old Sony 300, and the Panasonic A7 and JVC723 that I brought home to compare. CD play on the 9000, was better than DVD-Audio play on the A7 and JVC. With music, it's the best CD player that I've ever owned by a long shot, and with SACD, the sound is out of this world. It's smooth, detailed, and dynamic. I can use Dobly Prologic when I want to use all speakers when playing CDs or SACD, but in almost every case, I prefer crystal clear stereo for music.
With Neil Youngs' Live at Red Rocks DVD, I'm 50-50. If I desire to make it sound like I were there, I use the 5.1 DTS. Neil sounds distant the there's reverberation everywhere--much like the real thing. If I desire to listen to the music, I go Stereo. Neil is much closer, imaging is possible, and the music very clean.
