I was at the audio store, the better kind, and heard something very intriguing. The guy who I usually talk with told me, DTS works better with optical and DD works better with coaxial MOST times. We got on the subject when talking about my bedroom receiver(Denon) having a hookup for both and it will pick which is coming in best for a particular movie. He said most would be hard to tell but some are really better. Also I'm not talking the cheap optical either but the good stuff same with the coaxial. I know we have always said coaxial and I agree but now I'm thinking, especialy if the receiver does the picking. Confusion, whats your opinion or thinking of this?
