You will have to experiment with what is best for your room. In my main system my CS6s are aimed straight ahead but in my second system the CS2.4s are ever so slightly toed in. In my experience getting Thiels away as far as possible from the front wall is the most important aspect of peoper set up. This is what opens up the soundstage depth.
Thiel 3.7 Placement
Really considering perhaps purchasing these speakers. Auditioned them at a dealer for about 2 hours and was really, really impressed with the sound. My question is, even though I sat and toed the speakers to how they would be set up in my house, the dealers room was a lot bigger with no side wall infractions and the speakers were out about 7 feet from the back wall, so how sensitive are these speakers to placement? I can only bring them out about 2 ft from the wall and side walls are about 3 ft. Speakers will be about 9 ft apart with my position is about 11 ft in front, toed in centered right at me. That's how I have my B&W 802 S3 set up currently. Finally, how long did it take to break-in your 3.7's? Still happy with them? Thanks
