Here's one not so quick question for all you two channel people out there:

How does one optomize the positioning of speakers for best imaging? How far away should a listening position be? I have heard that if you draw a line out from the face of each speaker, the lines should cross about 2 feet in front of your position. Is this common practice? The result, however, is substantial toe-in.

My listening position is about 9 feet away from 2 bookshelf speakers (standmount). Are there any considerations about positioning on the stand itself?

Any help is greatly appreciated... Thanks
