Dear OP,
Putting your speakers on the far wall may not be the best plan. If I saw your room I could probably place them properly along the long wall (pun intended). That's how I have set the LRS up to great advantage and sound quality. But, they are maybe 8 ft apart in both cases. I use the room and reflectivity. The more recent placement I have also used filmy floor to ceiling length curtains behind which has been amazing at dispersing the sound. They were there already but I aimed them that way. Once again, long wall, but on the end of the long wall facing the short wall. Sitting in the knock out and way off the corner and the other corner created by the depth of a coat closet. Also sorry but I doubt your amp will do what my Bryston 4BSST can do with the LRS or any other Magnepan for that matter but then again not having heard it I may be incorrect. I had fed the LRS with 250 watts a side b4 and now with 500 they just sing. Bryston is the real deal. Buy one and sell that other thing.
