Once you have tried all the above suggestions to no avail, take into account the effect your room has on sound. Room treatments such as absorption and /or diffusion may help.
Using center panels on the wall behind your system often can improve focus and image. Absorption in corners behind speakers may tighten bass. Panels at first reflection points and rear wall will absorb standing waves.
But first you need a good reference recording.
