I would love to audition them first, but there are no dealers in Charleston, SC. I think the closest is 5 hours away. That's what makes this tough. I'll be building the media center around a speaker I may or may not get. I just don't want to regret anything later. I can deal with a shelf that's too big in the event that I don't get the 690. However, I'll probably be kicking myself if I like the 690 but can't get it due to the media center.
