Oh, and it has an industry-first multi-format disc player. It can read and play virtually any type of disc you feed into it: CDs, DVD audio discs, DVD video discs, Super Audio CDs, MP3s, AAC and practically every other format available on recordable CDs and DVDs. It even has the Bose uMusic intelligent playback system that uses tags to identify listener "moods" and calls up similar songs from the hard drive. Of course the speakers have been optimized for the 612, as well. The system looks fairly easy to control with two large knobs and an upper and lower bank of preset function buttons. Follow the read link for more details on the system.
