Optical connection between amp & DVD, is it any good ?

    Hi !

    I'm the happy owner of a Sony STR-DB1080QS reciever and a Sony DVP-NS700 DVD/CD/SACD-player. Today they are connected by a coax-cable. I'm very happy with the sound when playing both DVD's and CD's.

    But now I need the coax-plug on the reciever for a digital connection with my PC.

    Both the DVD and the reciever support optial-connections. Therefore I now intend to connect the DVD and reciever by a optical connection instead.

    The question is: Will this give me the same quality sound as the coax does ?

    I've seen several people (including the Sony manual), that recommend using the coax, because this provides the most direct route !?!

    Both cables carry a digital signal, and its this very fact that mean there is no difference whatsoever between the two,

    The only difference could occur if you were unlucky and had a bad cable, but this is unlikely.... Digital signals in this situation are extremely robust to noise, and I suspect if you were losing any 'bits' due to the cable, it would manifest itself as gaps in the sound, and other horrible artefacts...

    I am going out on a limb here, but I suspect anyone that tells you they can hear the difference is either
    A. Very much lying
    or
    B. Talking CAK

    - of course if the AMP is damaged, or the cable is, then sure, but this could happen to either...
    Oh and I;ve looked at several schematics for the Optical/Coaxial outputs on DVD players, and as far as routing is concerned, they are identical... they usually just split just before the sockets...

    Ken it is not regarded to be that critical in AV DD 5.1/DTS signals what type of cable type or connection type you use as the signal is [generally] regarded to be less prone to the effects of cable type or connector.

    But … If you are transferring music signals ie PCM coaxial is again generally more highly regarded than optical. So there is a difference, and I hope “I aint very much lying or talking CAK” when I say I have heard differences in these connections.

    BTW Here is an excerpt of my TAG DAC manual about the Optical toslink connection :

    I would take TAGs word for it that both types of connection vary and they may impact on sound, use a coaxial where you can but optical is just as accpeptable in certain types of transfer is bitstream.

    HTHs and of ocurse All IMHO.
