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.
