Dealing with the music first followed by the packaging....
The music - I've tried so far Animals, The Wall and Meddle. Animals sounded ok to me, quite a bit like the previous remaster, but nothing wrong. The Wall's opening track's drums sounded quite muted, not as bombastic as the previous edition (I checked) but other tracks like "Goodbye Blue Sky" sounded much better. Finally spun "Echoes" from Meddle and that just sounded alive on my system, I liked it. Its early days yet with a lot of material to go through, but on the whole there are a lot of positives about this release from real audiophiles who are more technical than myself.
The packaging - The box is okay actually, quite nice if you want to keep your discs in it. I think the flap is magnetic. The book inside, given the source material they have to work with, is utter crap. Over half of its 60 pages are dedicated to artwork from compilation re-issues and the MLOR and DB last Floyd releases. I have to say a major disappointment.
The CD's themselves are a bit of a lazy disaster. They are all gatefold sleeves, a bit like the Beatles Stereo remasters from a few years back, although they were tri-fold AND it was easier to get the artwork and disc out of the sleeve. These Floyd ones are an ABSOLUTE nightmare to get the discs/artwork out of them. Really tight and horrible.
The sleeve inserts also seem to recycle a lot of previously used sleeve art from the previous remasters.
I really wish EMI would of put some more effort in here. For someone buying single releases of these albums, this would of just about been passable. But for a box set I would of liked better quality like the Beatles mono set. I think they should of given this box set over to the Japanese to produce replica vinyl sleeves with inserts and resealable bags, oh that would of been wonderful.
So, in summary you should only approach this purchase for the music. The packaging is pretty terrible all-round I would say and really should of gone just a little bit further in its presentation, of what could be the last physical release of these albums.
If you do get this set, go the extra mile yourself and get some re-sealable outer plastic bags and anti-static inner sleeves from Japan (on Ebay) to protect your investment. Still won't change getting the discs out or the artwork, but at least you are protecting the cases and the discs as EMI chose not to!
