i prefer 2 ch for music and 5.1 for movies,although i have heard a few well recorded ,mixed 5.1 DVD A,SACD that sound very good!well done 5.1 music can be very exciting to listen to,ive found myself in stores getting ready to buy a 5.1 disc,only to put it back on the shelf worried that ill get one with a mix that sucks.i would buy more 5.1 sacds if they also included a 2 ch sacd layer instead of the usual redbook cd layer,,,
