Try cutting one octave lower -- i.e. 40Hz. Listen carefully. Sound should be "fuller" but realistic and nothing should be bigger than life, i.e. a cello should NOT sound like a double bass, a viola like a cello, etc. If it's too light sounding, go up by 1/10 octave until you get it right. If the opposite, go down by 1/10 octave.
