I was going to purchase the Shania Twain - Up album & saw it was released in SACD & DVD-audio. Has anyone heard either one of these or has anyone done any reviews that compares the two multichannel formats on this CD? Is one sonically better than the other? My DVD player has both formats. Also does anyone know which version of this CD is released on SACD & DVD-audio (pop or country)? Are they the same for both formats?
