I have several SACD's and I wish they would catch on more! A well made SACD is spectacular and eye opening. Favorites of mine include Steely Dan, Elton John, Pink Floyd, Diana Krall, Patricia Barber. Not all SACD's are hybrid (plays on SACD player and standard CD player) Also not all SACD's are 5.1 sound. Some are only stereo (ie most of Mobile Fidelity's SACDs) Actually one of my favorite 5.1 recordings is not SACD at all. Steely Dan Gaucho DTS version...fantastic. I have the 5.1 SACD version of this also, but I have to say the DTS is better. It has more of an "analog" sound to me. Smoother, richer sound than the SACD 5.1 version.
