So my copy of the "Sounds of the Universe" boxset just arrived. I was actually really pleasantly surprised with the amount of vintage synth goodness contained within. The pictures of piles of gear in the "Making the Universe" photo booklet alone will be enough to make most gearheads pee their pants in jealousy. The documentaries give a good look at some of the vintage synths used on the album too.
Even without the gear porn, this is a great boxset. The extra tracks include at least 3 songs that probably should've been on the album, the demos are really interesting to hear (Gore singing songs that Gahan went on to sing, hearing the songs before Wilder had a chance to do his magic to them...), the 5.1 mixes sound great, and the included films are very interesting. It's nice to see Depeche acknowledge their musician fans who are interested in their techniques and gear, though.
