Modestly I would recommend:
1) Beethoven Sonatas (complete)
- Brendel on Philips (the new digital recordings);
- Gilels on Deutche G. (not complete but several ones);
- Ashkenazy on London is sometimes very good also.
2)Mozart two-piano music:
- R. Lupu & M. Perahia on Sony Classical
3) Goldberg variations:
- G. Gould, the 1981, digital recording, on Sony Classical.
