Cabo Coaxial ou Óptico? Tanto Faz.

Acabou de comprar um Receiver e está em dúvida sobre qual cabo de áudio deve usar pra ligar no DVD? Não sabe se gasta $100 num óptico ou $50 coaxial? Veja o que a Dolby diz sobre qual cabo usar em sistemas 5.1

18. My DVD player has
two digital outputs, one
optical and one coaxial,
and my Dolby Digital
decoder has both kinds
of inputs. Which should I
use?

Under most conditions,
optical and coaxial digital
connections work equally well.
Under some rare circumstances,
however, coaxial cables, particularly
very long ones, can pick up
radio frequency (RF) interference
generated by household
appliances, or nearby hightension
power lines or broadcast
towers. Coaxial is less expensive,
so is a good place to start.
Note: some DVD players and
Dolby Digital decoders have
either a coaxial or an optical
connector. Be sure that the
units you purchase both use the
same type.

A minha escolha? Um RCA comum ligado como coaxial. Custou $5. Meus ouvidos reclamam mais meu bolso agradece.
