Argh, typo: I user Sennheiser HD380 pro headphones, did not use AKG reference.

I am sure I can rate all of them in order consistently; I am also quite sure I could show people what to listen to in order to rate the versions correctly. I will not do so in order not to impact the experiment, however listen carefully to: 1. sibilants 2. hats and crashes 3. the small hi-hat that plays on the eights 4. the splash cymbal (it only comes in at times) I found these parts to change very noticeably in the 5 versions. There were only two versions which I had trouble placing: I was unsure about which was the third best or fourth best. Listened on: iMac speakers and Sennheiser reference headphones. Didn't need to bring out a proper audio card and reference headphones.
