In the meantime I have received my copy of the RSD album from the States. I had no problem with getting a wav download code after writing two e-mails.
The sound is brilliant although there are no major differences comparing it to the CD remaster from 1999. Ladytron is a few seconds longer, the electric piano in 2 H. B. sounds a little bit stronger, especially when listening to the intro.
Was it worth 40€ ? I am not into vinyl so the only benefit of this is the CD I have burnt from the downloaded file. Sometimes it's hard to be a completist
