Has anyone done any critical listening to any of this material? Is there a master list of what has been released on DTS audio? It's going to be months before I can afford to buy my sweet DVD-audio/SACD universal DVD player. So, in the meantime I didn't have to wait to listen to Frank Zappa - Halloween that was released this year because it contains a DTS audio track as well. I don't know if it's something that's been around a long time or if growing/not going anywhere or how it compares to regular CD or DVD-audio so I'd like to hear some opinions. So far I am amazed at the sound of FZ Halloween and can't wait to get home to listen to it again I am curious if there are other DTS audio discs available and if they really do tend to use DTS's higher bitrate and if that results in better music quality. I believe that it's likely a poorer alternative to DVD-Audio so it's only whetting my appetite for what will come when I finally by my U-DVD player.
