Just for fun I listened to the opening movement of the 2d, by Ashkenazy/Haitink, Wild, Andsnes, Janis/Dorati, and Ogawa. I didn't have time to go thru all I have, ie Hough, Van Cliburn, Richter, Shelly, Ashkenazy/Previn. I included the Janis recording only because of its general rep and your preference for a Merc of Beethoven 5, I assume because of recording as opposed to performance issues.
My least favorite from a sound POV was Janis. The bass was boomy and the piano sound not sufficiencty distinguished from the orchestra.
The Ogawa would not meet your sonic expectations because the performance is too laid back. The recording is quite good however.
Andsnes' performance is the exact opposite of Ogawa - I like its leanness, a breath of fresh air from the overripe nature of so many performances of Rachmaninoff's music. Its a very good recording as well.
IMHO, the best recording for you would be the Chandos digital remastering of Earl Wild/Jasha Horenstein (get the 4CD set). The piano is tightly focused and dynamic, although it does have a spot lighted nature. The orchesta is well recorded, it is not drowned out by the piano. Nice balance. Now the best part! It is an exciting performance as well, one of my top favorites. I think you would love it!
