Agree with Rwwear - the K2 HD discs sound amazing. Even if SACD is potentially a better technology, the quality of the FIM recordings make them sound better than most SACDs. If you only have a Redbook player, this the best sound you will find. The downside is that most of the music is pretty obscure - mostly good demo stuff. Try 'The K2HD Sound!' sampler - tracks 1,2 and 16 are the best demo material you will ever find (if your system is up to it).
