Great show, Scott! I feel like it's been a while since we had a guest get so technical. I was waiting for him to refuse or hold back, like so many do, to which you always respond with something like, "No, please! The more technical, the better!" "JJ" would be an awesome return guest, especially if he ever gets to talk about the secret, proprietary stuff.

I would like to know how someone specifies what a room should sound like. I didn't really understand what he meant there.
