Michael, the QSS stands are a less than optimal compromise. They can't be made any taller, and still be stable. They are for those who may not have an other choice but to mount them on stands. If possible, try to get the QS8s at least a foot higher than your ears.
I'm not sure why it is preferable to get the them "slightly forward or rearwards of the listening area," as opposed to directly to the side. But, I have mine a foot or two behind my seating, and I love them there.
Many of us have to compromise when it comes to placement. What you do, is your call. Don't agonize over it. Do the best you can, and don't worry about it.
Edit: I HATE it when Tom is quicker than I.
