I would love to hear some feedback on the sound isolation that you're doing (including green glue). I know you can't do a A/B comparison, but would love to hear your feedback after the green glue dries/settles in. I read that it takes a week or more to cure and to become (more?) effective.

If I ever my the condo below me, I would seriously considering turning the basement into a HT (with sound isolation).
