For music I'll say nothing more, it is absolutely singular. I bought the box in the opinion, the CDs were remastered with new bit 20 or even 24. I had read somewhere this, not here on Amazon, so no accusation. The CDs are now but absolutely identical reprints of originals that also were indeed already excellent, but it is simply no longer. The only added value is the booklet with a few photos and an essay by Peter RĂ¼edi, all excellent as well, but in my opinion not worth 20 ... I therefore habs resold and hear still the old CDs. But who has not yet -> buy absolutely!
