Anyone on the list have an opinion on which is the better CD to get of Ashenazy/Previn on Decca? There is Piano 2 and 3 with preludes included plus the rhapsody on a theme of Paganini. Then there is all 4 concertos on 2 CD deal. I realize that one omits 2 concertos but I'm mostly interested in numbers 2 and 3 anyway. I thought I had read somewhere that the remastering is much better on 4 concertos deal vs. 2 concertos+ preludes. I would rather buy the better sound so if no difference I will buy the 2 concertos CD deal. If anyone has any knowledge on this I would appreciate any help on this. Glenn
