Depending on how much you want to spend and what your ear likes, I'd say the 300 is as good as most and better than others in its price range. As for mods, it is already filled with contemporary goodies.
Depending on the rest of your system you might be better off upgrading another part of your system. Is there something about your present sound that you don't like or want to improve upon?
