Hi
I recently entered a piano competition, the adjudicator always said to everyone, listen to recordings, people said they do listen to recordings of horowitz, gould, lang lang, richter, and he just replied with "listen to more" get an idea of how its meant to sound.
I think its good to listen to recordings of professionals playing, it gives you an idea of how it sounds, of course if you listen to a recording you dont copy them, you have to find your own interpretation, i played Heroic polonaise in the competition and i noticed, everyone that plays it has a different interpretation and speed, it took me along time to find my own!
So i think listening to recordings can't do any harm and is not cheating! listening to recordings often helps me get ideas of my own and helps me find me own way in playing the piece!
Good Luck
