I got mine on Monday, and finally got around to hooking it up on Tuesday night. The sound quality is quite good, but the operation of the unit is a little sporadic. I think a real manual, not just the Quick Start thing will definitely be a help. I don't really understand all the Audio Preferences, and the video adjustments (vertical/horizontal shift) don't seem to work for me.
I did, however, get the remote completely programmed for my system. I have been using an MX-500 for years, so the remote was really intuitive for me. I just had to figure out the ins/outs of using a PC to do the programming.
Sound wise, the only thing I've not been able to completely figure out is playback of my SACD discs. I have an Oppo DVD/SACD player that is capable of sending the MPCM over HDMI, or DSD over HDMI. When playing back a DVD-A, I choose DVD-A as the sound mode, and the display shows PCM 7.1. Cool! The problem is when I put in an SACD, there is no sound what so ever, when the sound mode is set for DVD-A. If I put it to DolbyIIX, I can hear the disc, but it doesn't sound to me like it is playing the 5.1 discrete channels. The display shows PCM 2.0. Maybe I'll have to break down and give a call to B&K.
