The quality of the SACD is well felt immediately on registration; The dynamics and micro-information stand out much better than on the normal version (or vinyl that I also own). I do not regret my purchase, nor that of my SACD player entry, which gives me more (musically speaking) my other High-end drive (15 times the price !!!) but which bed not SACD. Too bad that this technology has been long abandoned. Jean Paul
