It's funny that people comment on the small table and not about the bare walls. I doubt that you want to cover the whole wall with acoustic material, but some fabric decor (for high WAF!) in strategic places might do some good for mid and treble emphasis/brightness.
You may need a second person to move the "panel" across strategic spots that seem to reflect towards the listening position. It will be a long trial and error session but it's a good start. Only after solving that basic problem should you look at equipment and/or cables for additional enhancement.
