I have been a Tangerine Dream fan since the early 70's. I was on the fence about buying this, because I have all of their CD's. And I mean ALL (well over 100!). I didn't have a surround system yet, but I bought this when it first came out, because of all of the extras, and in the hope I would be able to play the 5.1 mixes someday. Well, today is that day. And while I didn't get the great deal that some got when buying this box set, I am certainly glad that I did. The Steven Wilson mixes are all incredible. It's hard to believe that I first listened to Phaedra nearly 50 years ago, but the new mix was like hearing it again for the first time. Very immersive. While I always preferred Ricochet, and the new mix of that is also excellent, there is something about the Phaedra mix that makes it my new favorite. And, I was finally able to hear the holy grail of Tangerine Dream releases, Oedipus Tyrannus. It sort of had a Zeit vs. Atem vibe, but it showed the interesting transition from the Phaedra album to Ricochet. Again, the mix is stellar. These are among my favorite and what I consider the best of Steven Wilson's 5.1 mixes.
