The Demy set is wonderful, and I'm thrilled to have it. My only slight disappointment is that the audio on "Young Girls" does not appear to be as clean or sharp as it is on the 2-CD set (Philips 558 408-2). In fact, I had to use headphones just to verify that the Blu-ray was even in stereo. It is, although the separation is very minimal, whereas the CD has a much wider stereo field and sounds fantastic. Not sure what elements were used for the Blu-ray. Minor quibble. It's great to have these films beautifully presented.
