Whats the advantage of connecting your consoles to your amplifier/receiver through HDMI and then with another HDMI cable to your TV as opposed to connect the consoles directly to the tv and then with optic cables to the amplifier/receiver? My tv is a 40" Samsung UE40C8705 LED 3D TV and my consoles are ps3, xbox360 and Wii. I am currently trying to find a surround sound solution that will utilize all of the various machines capabilities. Any help much appreciated.
