Some high WAF options here: ( http://www.audimuteacousticpanels.com/home-soundproofing ) (http://www.audimuteacousticpanels.com/acoustic-panels) Regarding your listening position: Against a wall may be great in a cave, but it's the last place you want to sit, listening to music(very bad for accurate bass reproduction, via peaks/nulls). Some good guidance here: (http://www.realtraps.com/art_room-setup.htm)

Mr N: Yes, near-field listening could be making all the difference. Especially in a small room. Also, you may have a null(narrow enough or at a low enough frequency), against that back wall, that doesn't affect your perception of bass reproduction. (http://www.realtraps.com/art_small_rooms.htm)

Happy listening! =;^)
