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

Speaker positioning requires a lot of patience IMO.   It's taken me months to find the right speaker position/listener position for my S5s.  Play around with toe in to get the 'best' balance of imaging and soundstaging (best being what you like most).  Once you think you have it, then maybe consider adding some treatments to the wall behind the speakers.  I use Vicoustics and it has really helped deepen and widen the soundstage.

Remember, have patience, and good luck!

I agree with all the above posts but would like to add - measure from your seating position to the center of the speaker base. I was amazed at what an inch or two can make. From there start with no toe in and adjust from there a couple of degrees at a time. As you adjust the toe in also verify the seating position to speaker base.

Look up how Wilson Audio teaches their sales reps to set up speakers. A lot of people bash Wilson's but their setup technique works. It's real simple, and it's using your voice with your ears.

I would say the speakers are too far apart. From what you describe the speakers are 10 feet apart with you 13 feet back. I would start with the speakers 6 feet apart (centerline) pointed straight ahead with the listening position 8 feet back, then moving the speakers further apart until the center image begins to break up. Then experiment with toe in and listening distance.

OP,
My room is slightly smaller than your's. But my positions are very close to what newbee has mentioned. Start there and also keep in mind about the toe-in. That also needs to be accounted for. Like everyone mentioned - it takes a few hours to days to get the perfect imaging.
