Yes, much cheaper than the Oxygène box set, and probably better build quality too... I'm definitely going to get the German edition CD box set... It will be a bit different from the albums in English I have. Plus the track order is a bit different, and it will be a nice update from the originals and since the tracks are sometimes shorter (e.g. Autobahn is 14 minutes instead of 24) it cuts down on the repetitiveness that can be boring at times - although that was intended.
I'm sure the mastering will be better than the Electronica / Oxygène series. If they are able to keep the crisp, spacious sound I heard live in 2015, this set should really be a treat.
It will also be interesting to compare the "3-D sound" of the Mix album and that of the few Electronica tracks that were released that way. Again, if they are able to do 3-D with sound like they did the 3-D visuals that should be very interesting. Before going to the show I thought this 3-D business was a gimmicky ploy, but it really works well!
