In short: if you interesiert for Abba, this box is a must-buy! However, some reviews here show that there seems to be false expectations. Even if all the ABBA CDs has already 1-2x, it is worth namely very !! What exactly is this box ?? She is: 1. A collection of real everything was published by ABBA so far, including all foreign-language versions, alternative mixes for maxi-singles, etc. as that which has been released on Rarities on various compilations. 2. More importantly, the material is sonically possible for the first time !! The Polydor CDs from the 80s have been pretty dull and lackluster, and much worse were the remaster of 1997/2001. Since the infamous Jon Astley has everything to digital registers Nahbearbeitung drawn (mainly loud). Well, quietly this box set is now just not, but: Still, it sounds pretty great. Will again certainly not remastered for the foreseeable future and I think that with this version, you can live well. The "Thank You For The Music" - Box sounded pretty good, but that is indeed now time not completely. 3. It is presented beautifully. Velvety Box and exact replicas of the original albums, finally again with the original lettering. The Abba lettering of Arrival-days indeed had by now landed on the previous albums. And the two DVDs are also a great addition. New rarities there is not really self-understandably !! Schlißlich the concept is the complete collection of everything that is published and what you get otherwise practically no longer collected. And - Abba collectors: not underestimate the aural profit !! It's not just about having the songs ever, but also how. And at Abba sometimes helps unfortunately not even the original vinyl, which also did not sound all great.
