This is my sound system, it's not Klipsch, it's an Australian brand, Krix. The mains are the Euphonix, and the rear's are Equinox's. I don't have a centre or subwoofer, yet. I use a Marantz SR-96, Marantz DP-870 and Millennium dts decoder, a pioneer 414 dvd player. I'm seriously thinking about changing the speakers for the Klipsch RF-3's and then add the RS-3's and RC-3, and then I'll wait for the RSW-15 to see what it's like if it's good, I'll take it, if not I'll go with the Velodyne CT-150.
