Christian, one listen to the two will tell you a lot about the SQ of these two pressings. IMO, ( owning both) I believe that the US pressing is far more resolved and has a much better stage. As to the quality of the pressing, again IMO, the US pressing is much quieter. The other difference, which you have not mentioned is the pressing number...a typical 1s 1s US pressing will sound better than the same LP in a lower number pressing, i.e. a 10s 15s pressing.( Nonetheless, I believe that a lower US pressing will still sound better than a UK pressing) As to collectability, I believe that all of the US pressings are more collectable than the UK re-issues. SQ, at least IME, is also always preferable in the US pressings vs. the same UK pressing. This does NOT apply to all US vs. UK LP pressings ( non RCA).
