Wow, I can only imagine the shockingly pristine sound of those multi-amped ATC's! Relating to the previous question about placement near the rear wall, that was the issue that led me to acquire my much more modest ATC SCM19's. They aren't very picky to place, and I had no choice but to actually cram them into a bookshelf.
Any way, a beautiful system you have. Tasteful AND opulent at the same time. Well done.
