The original 12" does sound good, like most Posford releases always have. I've been meaning to compare all these tracks since I bought the new vinyl box, but never got around to do it. But today after work I did a quick listen on Space Pussy.
From what I heard or read, I don't remember, they didn't want to change all that much. Not getting into the loudness war, 1.0(radio/tv) or 2.0(youtube/spotify). Kevin Metcalfe knows what he is doing, he has been working with Posford for a long time.
Everything sounds a bit clearer, not much but still. The volume on the remastered version is a little lower, which I take as a good sign. All the small details is not lost, rather enhanced. They did a good job with it. =))
