Digital Coaxial Cable vs Analog RCA Interconnect

Hi all,

Just want to ask all home theater otais here, is it possible for me to use Analog RCA interconnect for coaxial output form dvd player to receiver?

and which is better Coaxial or Optical for HT sound purposes?

Please use coaxial 75ohm cable only for digital cable. Although some Analog RCA cable is 75ohm coaxial. For HT sound purposes you can use glass optical cable which sold at ebay is cheap & good. Normally better coaxial cable will more expensive than glass optical cable. So coaxial will better than optical, but you need pay more.So far The best coaxial cable in reasonable price is Veloce black cat digital cable.
