Need advice for soundproofed home theater. Projection screen 200" diagonal. Listening distance from front speakers to sitting area approx 30' crossing the dance floor. Currently thinking of the B&K 200.7 preamp driving a 7 speaker Sonus Faber Concerto setup. Will use the top line Velodyne sub as well. This room will be used for cinema as well as my music room. I have varied tastes from Sting to Miles Davis. I would appreciate any advice from you audiophiles collective listening experience. Thanks
