Long, long ago, I thought it would definatly "hurt" my interpration of a piece when I would listen to a recording of it. I thought I would sub-consciously imitate it, thus making it not "my" piece. And I think this can happen to you. But only if you are interpretating your piece sub-consciously in th first place.
That means, if you are really thinking about the way you want a piece sound, no recording can "harm" that. Furthermore, I don't consider myself better than the great pianist, so why not listen to them and see what they have to say about the piece. Of course, when you only listen to one and the same interpretation, over and over again, and don't think a second about your own playing, you may play like the recording in the end. But when you listen attentivly to several (>3) recordings while looking at the score, you will hear so much nuances, that you will not be discouraged but to the contrary be stimulated to try it, to see if you can do as good. I think listening to the masters of piano playing can teach you a lot.
When you then have listened to some recordings, you have several advantages:
1. You know the piece (by ear).
2. You know also what every section you listened to sound like, so you can imagine even the hard sections you could not play at first when starting to practice.
3. You know a lot of different possibilities on how to play this piece. You know that you can play this passages so or so, how you could handle the dynamics etc.
4. You also have a direct comparison to your own playing, which ensure a better control.
This does not mean that you should just imitate the recordings, coming up with a mixture of what the others played. It is more meant as an inspiration and a help (especially for not so experienced pianist). If you now, that you know several interpretation, go again through the score, analysing the piece, trying to understand why the performers played in their way, you will automatically agree with them, or not. And so you will gain your own interpretation. And if you can't come up with a better realization of this interpretation than Richter, Horowitz or Rubinstein, than well, why not trying to imitate them (if it's the best you can think of).
On the other hand, listening to recordings (escpecially for advanced/professional players) is no must. You can easily play a piece never heard before - why should you not? It can also be fun to try it on your own, to think of possible interpretations for yourself. But if someone other can convince you, that his playing is "better": why be so stubborn and stay with your playing? Just because it's yours? Do you want to be a better musician or a better narcist?
