Speaker Placement


Hi
I just finished my Audio Room and need help regarding speaker placement. The room is 20ft long by 16ft wide with ceiling height 8ft 9 inches. This is located in a basement all poured concrete. The front half of the room is carpeted while the back is wooden floor. If I sit facing the speakers the right wall is all uneven stonework and on the left I have placed some DIY panels at the first reflection points. Behind the speakers I have placed 2 DIY corner traps. So far the ceiling is bare and I have no panels behind the speakers. I have placed the speakers 3ft from the side wall and 4ft from the front wall all measured at the centre of the drivers. While the sound is very good (no bass bloat ect.) I am unable to get a good sound stage.  The seating position is about 3ft from the back wall. 
My 2 Ch. equipment is as follows. 
Speakers B&W 800D (Not Diamonds)
Power Amp Krell KRS 200 Mono Blocks
Pre Krell KRC 3
Sources Cambridge Audio Stream Magic V1 and Clear Audio DC Performance with Dynavector D17.
Phono is Project Tube Box DS. 

I just want input if this sounds right as far as the placement goes. Should I try and move the speakers closer together? 

Thanks

Guys thanks for your responses and some very helpful tips. 
Tim to answer your questions. 
The wall behind the speakers is the 16ft wall. 
The carpeted area is where the speakers are placed. It extends beyound the speakers about 6ft towards the listening area. 
There is one sofa in the room (3 Seater) in the listening area and two rather large chairs with cushions in front of the sofa. The chairs are in between and forward of the speakers (not directly in front.
There is one window 1ft*8ft on the left close to the ceiling. More of a skylight. Does not open, just for light.  The seating position is about 12ft from the speakers. 
I would like to tune the room so that it has a more generous "sweet spot" as compared to one within a few inches of one single position. Audio is more of a communal experience with my children and friends usually joining me. I would like the children to experience what a decent system sounds like compared to the MP3 they usually listen to. 
Thanks
