I see most are chipping in for the SVS, so I will just throw in something else to consider. About the international power requirements, HSU's VTF-1 also has 120/220 capabilites. All you need is to flip a switch and change the fuse (it has an external access point for easy switching). I know because I went that route (my work has me relocating every four years, more or less, and I never know where to, so I had to have the power option). It also sounds great with my Axiom fronts & surrounds! Your room is bigger than mine, from what I can see, so maybe a bigger model would be necessary. Out of curiousity, which model speakers do you have??
