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

Agree that there's no substitute for playing with placement, but the good news is that, unlike most things in this world, it's free.  I'm very into the 3D holographic imaging thing, and my room is similar to yours except 3' more narrow.  In case it's helpful as a starting point, after many hours of fiddling with placement my speakers ended up 5' 3" from the front wall and 5' 3" apart both measured from the front center of the speakers and speakers toed in so they aim toward my shoulders.  Obviously many many variables here so your results may vary, but I'm getting very good imaging and soundstaging with this positioning so maybe this could be a good starting point.  Hope this helps and best of luck.
