I took time to comment on this mainly because I wanted to listen to the other versions mentioned. As far as speed goes the order is Ashkenazy, Richter, David. What is my conclusion? In the Askenazy I find the accompaniement is the right speed but I did lose the melody now and then, while in David's I find the melody sings freely, but the accompaniement is too busy. Is this not something that is to be laid at Rachmaninoff's door rather than saying it is the interpreters fault? Did Rachmaninoff record this one? The open lid makes for a much better sound: a good choice, David! As for rerecoeding, why not? You have evolved since you did the last ones and you have new ideas: why not continue? I do find, however, that for a site that caters for non-concert pianists, there are too many comparisons been made between site members and the great. David is held up to Richter and Ashkenazy and I have been compared (not to my merit and may they never hear of it in the Pianism Fields) to Haskil and Gilels. Of course David chose not to follow a career while I was too late even to contemplate one, but that is neither here nor there. I also feel that any of these concert names benefit from sound engeneering and piano quality none of us here can hope for.
