I would like to clarify that I do not share the opinion either way that it is big hands that makes this piece 'playable'.
You could rightly argue that if you're using hand-size as an argument to playing this piece, you already don't know the technique involved, which is the facilitation of the wrist and rotation to enable your hands to cover distances they couldn't cover with a stretch and reach motion.
However I thought it would be a nice point to highlight that it is clear here that hand size is not what playing this piece is about, and even further, if you have particularly small hands, with some thought, this piece is still not out of your ability.
Compositions by Rachmaninoff however...
