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
srafi

Hi Srafi
Lots of good recommendations from others. 800 series need about 10 feet for the drivers to align. I would do this in about 4 steps. 

1) I would start with a 10 foot triangle, with the drivers pointing straight out and the speakers at least 5 feet from the wall. From there I would move speakers and chair together - toward or away from the front wall and listen.
Once complete.

2) You can begin moving your chair further away (if desired) and listen.  

3) Start angling them in. Horizontally.

4) Adjust for rake. Vertical. This will affect the smoothness heard at the listening position and the imaging height. 

See also this link from Patrick at B&W for some more placing tips, adjusting rake (tilting forward or back in the vertical plane)

Have fun and hopefully you get back to listening to your music soon.
