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

If you start with the premise that most speakers are too far apart (one supposes because somebody assumed that placing them far apart would provide a bigger, wider soundstage) then you’re on the right track. If you start out with the speakers much closer together - say 4 feet apart -then use the speaker placement track on the XLO Test CD which if memory serves is actually the out of phase track, moving the speakers very gradually apart and listening as you go you will undoubtedly discover the placement where the sound all comes together. When I had Fulton floor standing speakers that sweet spot turned out to be five feet apart.
