Good (controlled) bass can often sound lacking from smeared (tubby) bass at first. Further improvements to your system then eventually deliver bass textures , decay and ambient cues from the recording venue.
Like others have said , look to improve your power supplies and grounding for good bass (and good everything else for that matter). Then vibration control.
Assuming you have your room / speaker positioning application correct.
