Thanks to all for some great points to ponder. I've decided to stick with CDs. I am a huge fan of SACD - I have 6 or 7 titles so far, and will buy more, for sure. Additionally, I have been replacing some of my favorite CDs with remastered versions. So far, I have had excellent luck - hearing considerable improvement over the original CDs. If the source material sucks, the "best" system in the world is not going to do much to make the material sound great. Hence my focus on quality CDs / SACDs. Thanks again all - really appreciate it!
