I purchased Aerosmith's O, Yeah! Ultimate Aerosmith Hits today. It was in the clear and gold SACD slipcover with "Multichannel/Stereo" printed on it and it also had a "Single Layer/Multichannel" sticker on the outside of the shrink wrap. But when I played it, it only offered stereo. Fine print on the spine says "stereo" which I totally missed since I was looking at all the other stickers. This is a great sounding stereo SACD, but I should have got what was advertised on the package.
