You ask "Assuming you dont have HDMI, why do manufacturers use plain old RCA cables as an option for multichannel input? Why didnt they use 3 (or more) optical or digital cables instead?"
The answer is simple. Optical/coax connections do not offer content protection (i.e., HDCP) which is deemed essential by the content providers. That said, Meridian does do this but, for higher than CD resolution, it is encrypted.
