What is your player and/or processor? Maybe the DTS decoding is better executed in your decoder than the SACD side; I find that hard to believe, but possible, assuming your SACD player is a lower-priced model. As FMW says, the resolution of SACD is worlds beyond the lossy DTS stuff. OTOH, although I don't have an SACD counterpart to compare it to, my DTS copy of Lyle Lovetts' Joshua Judges Ruth is still one of my fave hirez mixes, and I own 100+ SACD's and DVD-A's. That's not to say the SACD version (doesn't exist) wouldn't stomp on it, especially given my Modwright universal player.
