What I have learned....

Over the years I have invested in a primary HT setup, but recently have used it for far more music playback. One mistake that I made early on was to modify my settings to make for a better HT/movie playback, which often jeopardizes the music playback in Multi-channel ( I am speaking about DVD-A and SACD here). Because of that fact I have recently starting thinking in opposite terms and have set up my system for optimal music-listening and have realized that it does not dramatically effect the movie playback, which was just the opposite. So my recommendation is this...

If you are using your system for both Multi-channel music and Multi-channel movie purposes...I would calibrate your setup first to music-only programs instead of setting it up for movie playback.
