Bill,
Not sure what kind of bliss you are trying to achieve, but your current setup and gear should be giving you just about everything one asks for in a "home theater". The only minor thing I see is the in the bass dept.. As mentioned before in a room that size it would be best to add a nice sub (JL Audio F112, B&W ASW 825, REL Stadium or SVS PB Ultra 13 & Epik subs )and maybe use your current sub in an alternate area in the room (maybe the absolute rear). This should give you the in your chest feeling during most scenes if you are not experiencing it yet. HSU subs are good too, my buddy has one and I love the deepness his produces, but his setup is purely musical and not HT.
