Hello Charles,
Thanks for your reply comments above and compliments on my system. Like you, my music room is also a finished basement of similar size: 14'*21'*7' and I also use 5/8inch drywall (on isolation clips to prevent energy transfer to the ceiling and floor surfaces) and Roxul and one other kind of sound insulation in the walls. I'm glad to hear that you like the alive and dynamic sound presence you get in your room; I've gone to great lengths to prevent overly absorbing mid/high frequencies for the same reason, hence the liberal use of diffusion and adjustable side wall reflecting baffles.
I believe your Coincidence gear is built in north Toronto where I work - now that's a coincidence! I once heard their gear at the Montreal stereo show (Son & L'Image) and it was very good sounding, just a bit pricey for my budget.
