"I do know it's lacking compared to higher end setups I have heard but again, nothing I can enumerate."
You have a serious problem. If you cannot describe what your system is lacking, how can you expect to fix it?
As a first step, you might consider having a pro come in and sonically audit your room. This will at least point out any problems the room my be causing and may help to pinpoint a solution for you. You may be able to do this by engaging the help of a fellow Audiogoner nearby...Where do you live?
