Harbeth 40.1 - Need some tips on placement from current owners.

Love to hear some tips on ideal placement. I have a 19 x 24 foot room with the speakers on the short wall. Normal 8 foot ceiling. They will be on carpet over concrete. I am thinking of bringing them out 7 feet from the wall behind them. What about nearfield listening? Toe-in if any? Love to hear some comments. Thanks all.
