I have compared all three of these format and find that the amazing sound staging goes away with 2 channel SACD and Vinyl. Many of the surround-sound-like effects apparent with the redbook CD simply disappear. I wonder if the effects were accomplished with precise phasing that is not preserved in the other formats, or if they're may be 180 degrees out of phase?
Has anyone else noticed this? BTW - I have not heard the SACD in multichannel.
