Where should the vocal image be?

Some one made the comment about room acoustics.  In my observations, room acoustic improvements make changes in the plane you apply them on.

To improve depth, focus on diffusion behind the speaker and listener. Width, absorption and diffusion to the sides. Height?  Floor and ceiling.

Credit on Audiogon really doesn't mean anything, people will still misspell your name even when it is right in front of them. 😂

behind the speaker plane. :)

but this is extremely recording dependent.
