First of all, thank you for welcoming me to this great forum.
In response to your questions I now have my system info and the preferred music in my profile.
Regarding the rest of the room, walls are wood-paneled, ceiling is plaster with exposed wood beams, right now the floor is covered with a nasty carpet on top of the cement slab. Carpet is coming off soon, and it'll probably be replaced with hard-wood with a couple of rugs thrown on top.
It warms my heart to know that I can put the K-Horns along the long wall. It's been a dream of mine to acquire a pair for a while now, but the space we lived in wouldn't allow for it.
