I will not repeat the titles but the sound quality of SACD edition. Indeed, mixing in 5.1 SACD is quite remarkable and provides superior immersion to stereo listening, without distorting the audio message. If you're a fan of the group, are equipped with multi-channel audio and have an SACD player (or Blu-ray compatible player, such as a lot of Sony and Pioneer drives), I think you will not be able to hear otherwise!
