Have you tried using a thicker gauge string. Or A different brand, or material.... The string itself has a major impact on the sound - fiddly light strings are comfortable to play, but will sound weak too. Obviously too thick, and your fingers will hurt - but if you are serious it is worth using the thickest ones you can. Your tone will only improve!
