Its okay if you are a floyd die hard. I bought the CD and the sonics are very good for a live recording. It is better than the Pulse CD for example which is a much more recent recording. It has good soundstage width and depth, though I find the sound to be quite mid-bass heavy and a little boomy in places. If i'm in one of those 'wall' moods, like after too much Gin, I would sooner listen to the original.
Incidentally, I have a reasonable hifi rig and the best non-vinyl floyd sound that i've heard is Pulse on stereo VHS. It is incredible, non-fatiguing, with excellent imaging and soundstage ability.
Anyway, there i go again......
