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

Congrats on your room, nothing like a dedicated room for 2 or multi channel!  You mention your ceiling, what is it?  Finished? Flat or are joists exposed?  I find the floor and particularly the ceiling are the biggest problem with reflective sound.  

And what are you missing in the sound stage?  Specificity of imaging?  or instrument separation?  holography?  Generally the more space between your speakers the more of these characteristics are enhanced.  Closer the speakers the narrower the stage but it can give a more rich presentation and stronger image. 

Yogi is right about speaker placement - if you have not spent many hours moving them around you will never find the sweetest spot.  Sounds like you have plenty of room to experiment.  Personally, I am more about the tone and balance than soundstaging qualities.

Good luck - now get to work moving those B&W's around!
