OP and others, thanks for all the useful and interesting information. Incidentally, we are in the process of getting our roof deck foamed for better energy efficiency in our hot, Phoenix summers. Never thought that better sound would be icing on the cake. Now I'm even more motivated.
The best room upgrade: $2250
I live in hot as hell Sunny South Florida. My house is open beam ceiling (no attic). Upstairs without air conditioning on is 95* +!
I finally got around to getting the roof Siliconed to knock down the heat and UVs= lower electric bill. What I didn't know was the impact it would make, quieting my listening/TV room. For the first time in 25 years, no traffic noise from nearby I-95 and I-595!!! And when I turned on the TV the sound was relaxed, not echoing in the room. I haven't yet put the stereo on, but will later today
Glad I did this before my Voyager amp arrives- any day now. I need to get a handle on how this changes the sound before I put in the system
