I did get my set, and here are some of my thoughts.
First of all, as others have mentioned, it is quite expensive for what you get, but for me, it was overall still o.k.
I have read some comments regarding that many people didn't like the mix of digital media with vinyl, and I can totally understand that (I was the exact same before I went back into vinyl). But since I got back into vinyl about 10 years ago, now I really don't mind it if they combine the different formats in that way.
The main thing that I really wanted was the US Quad mix on a physical disc, and I think the transfer is nicely done, and I am really happy that I finally own this mix on a physical disc.
I was also interested in hearing the new surround mix, and I think it is not bad, but also certainly not as good as the Quad mix. It does offer a few interesting things, and the new surround mix is at least also retaining good dynamics. Perhaps I will attempt to make a stereo downmix.
The other thing I was quite interested in is the live recording from 1971. It is not too often that we get an unreleased concert recording from the classic line-up. And despite some comments here, I actually think the sound quality is quite good. There is a bit of a sound problem shortly after "Speed King" started, but it gets fixed quicky, and then it sounds actually good to me.
It doesn't sound like an audience recording to me. way to defined and too much clarity, but I could be wrong. It sounds almost like a mono mix from the soundboard, or perhaps some kind of combination, I really don't know, perhaps it is an audience recording, and it was EQ'd accordingly to make it sound better. It sounds warm, full and clear to me. And most importantly, the dynamics are still there, it was not dynamically compressed very much (unlike the '72 live recording in the set). So that CD (Montreux '71) represents some real value for me also. I also like that Ritchie's guitar sound during that time is less distorted, compared to - for example - "Made in Japan", so you can hear some nice Fender Strat sounds reminicent of the tone Jimi Hendrix sometime had, for example during "The Wind Cries Mary".
The other CD's are not that great, mastered quite loud. The concert from '72 I already have in better sound quality, as well as the original mix. Too bad that the new stereo mix is mastered quite loud on the CD, and it is not on the Blu-ray (a little bit disappointing), but here comes the vinyl, that will be my "high-res" version of the new stereo mix. The vinyl pressing is of good quality, flat, well-centered, and no playback issues or pressing defects (such as non-fill etc.). And the purple-smoke-colored vinyl looks actually really nice. And I really like having "When a Blind Man Cries" on there before "Space Truckin'", I love that song, and the new mix is really good for that song, I think.
I also think the booklet is quite nice, with some pictures I haven't seen before (not sure what people were referring to when they said there is no real booklet with the release). And the cardboard slipcase is also sturdy, and I don't mind this type of packaging, it doesn't take away too much space on the shelf.
So, all in all, a bit on the pricey side (maybe around 60-70 Euros would have been more appropriate), but also not totally overpriced either.
If this is an important album to you, then it is a nice release.
