Hi,
Yup. My point is perhaps best descrined as:
There are several possible and achievable solutions to achieve a given goal. Which one is preferable depends usually on the context.
If you can dedicate a complete room to nothing but audio, no wives, pets, rugrats etc allowed and accept looks as completely secondary to a given sonic result, then you can add as much acoustic treatment as you like, 8 pcs of 24" Subwoofers, one in each corner, you name it.
My problem is that to me such a room and the system in it would be in essence a pure obsession with minimal use. I prefer my system to be in the room that I am usually in, which means I need a good bedroom system and an excellent living room system that can still be heard loud and clean in the Kitchen. 
I observe similar thing with other friends who have serious rooms and system dedicated, they end up listening most to the secondary (or tertiary - if they have two "main" systems in the dedicated room) system in the living room.
Don't get me wrong, the dedicated systems in the dedicated rooms are usually utterly stunning sounding and notably better than what I have at home, but the secondary systems tend to be often much worse... ;-)
Ciao T
