Kr4, I agree. IMHO, Ashkenazy/Decca by a considerable margin. It comes with a very good Isle of the Dead as well.
In fact, I prefer his Symphonies as well. They are just more taut than Previn's, and most others except Pletnev, which suits me fine. His PC's w/ Previn are also excellent as are their Suites for 2 pianos. Even Ashkenazy's solo piano works are excellent. Ashkenazy rules Rachmaninoff! or at least almost rules. :-)
