I currently do not have a pre-amp or receiver that will allow the connection of the HDMI cable. So for the moment, I am sending only the HD video signal to my LCD TV. I have some sort of a mental block. How can this one cable deliver the same quality sound as six separate high quality cables and produce a high quality resolution picture at the same time? I know that the signal stays more pure not having to transfer from digital to analog, but how is the HDMI really better in regards to sound?
