I own sep. SACD and DVD-A players because I had to jump into multi-channel as soon as I could. They are both very good (at least IMHO given my not so very good monitor yet) DVD players as well. But...I wish (primarily due to hook-up situations, only one set of multi-channel inputs and no affordable multi-channel swithes around) that I had a really good universal player.
So if I had it to do all over again...and given enough time I probably will, I'd look into the best universal player I could afford.
