My CR-1's are 2 feet (maybe plus a few inches) from the front wall and almost cross-fire in front of me. They are probably a little further apart than TAD recommends, but as time went on, I'd move them in tiny amounts. All in all, I am very happy with the sound. I do like to switch gear around to mix up the flavor. The Dartzeel combo seems the most detailed yet natural sound I've heard from the TAD's. I get more excitement from the Dagostino and it's nice to have choices. I don't think I'd ever be satisfied with one system. The tinkerer in me can't leave well enough alone. The highs on the TAD's from my Burmester gear was just a little too much for me. I don't get that from Dartzeel or Dagostino.
