De-Naimification Complete!! I Feel Cleansed...or do I?

Hmm. In most room firing across works better...

Totally disagree. It depends entirely upon the type of speaker, room environment, shape and size and not least, how wide a soundstage you want.

Simplistically, the best room shape is rectangular, preferably with irregularities like crooks and nannies to break reflections. Square-ish rooms, unless very large, are tricky, and usually proscribe electrostatics , rear-facing ports and some other ported speakers as well as a great many large floor-standers. Ceiling height is also a factor.

it is impossible to make generalisations , you have to experiment , as far as is possible with speaker and listener placement.
Loudspeakers with boundary filters obviously increase your placement options.
Use acoustic measurement to compare options.
