I'm new to multi-channel audio, and with the 2+ formats available, DVD-A, SACD, and DTS (DVD-A that uses the digital out!), it is quite overwhelming. I don't have multi channel inputs on my Lexicon, so I can only play SACDs in 2-channel format (I have Sony's 999ES). I am pleased with SACD stereo, but I can't help but wonder how much better multi-channel SACDs would sound. I really like the idea that DTS uses the digital out on CD/DVD players, but I have no idea if their sound is as good as SACDs or regular DVD-As in multi-channel. I just bought Vivaldi's Four Seasons on DVD-A (DTS), but I'm not very impressed (and I'm a HUGE fan of DTS Movie Soundtracks!). Are there great sounding DTS CDs out there? I'm wondering what format you guys (and gals) like the best. Thanks!
