A few of the high end magazines like stereophile say that the biggest advantage to these players is running the multiple dacs in parallel while in 2 channel mode. There was an article that featured the opinions on multichannel music from 4-5 high end retailers in NYC. It was an interesting article. The consensus was that 2 channel would remain the high end playback preferance while multichannel would mainly be adventageous for low to mid/upper level and video. Other articles have pointed towards running all the dacs for 2 channel operation. Great results apparently.
