    Toslink question: glass vs. plastic

    I apologize in advance if this causes a stir although that is not my intention.

    I recently purchased a Behringer DEQ2496 which I would like to hook up in the digital loop of my Transporter. So, obviously, I'm going to need a couple of toslink cables. So I do a search on a few different forums looking for a no-nonsense, not-terribly-expensive-but-good-quality toslink cable recommendation. Lo and behold, there's yet another great debate: plastic vs. glass. I didn't see this one coming but I can't believe I was that foolish. I should have known better in the world of audiophilia...nothing is ever that simple.

    I've never had the need for a toslink cable before as I've done all of my digital cabling with coax up until now.

    My question: does it really matter for a roughly 3-6 foot run of cable?

    Thanks,
    Joe

    Why not just try it out?

    Audiophiles swear by glass - for me the difference is negligible to non-existent.

    The main problem with optical toslink cables is generated jitter. I haven't come across a study stating that glass intrinsically generates less jitter... But you'll need good cables, that's for sure.

    PS: unfortunately I can't get a hold on the measures of optical cables' generated jitter, but (as far as I remember) it was quite impressive. Perhaps someone else will provide a link.

    Why, for such an easy application? The Behringer's doing a lot more to the signal than any cable does.

    I guess I meant, try out plastic and see if it sounds bad...

    FYI, you can use coax with the DEQ2496, you just need to hook it to the AES/EBU connector with a balanced xlr on one end and a RCA on the other.

    The manual covers this, you have to short two of the pins (1&3 I think... can't remember) on the xlr side.

    I've done this with a custom cable I put together, and it works just fine.

    Why is that obvious?

    I use the Balanced AES/EBU - I just use a couple of XLr-XLr cables I
    made myself. Sure, they're supposed to 110 ohm, but they seem to work OK

    You are probably right, simply I don't like buying cables that I'm obliged to throw away, after initial use.

    bluejeanscable.com sells plastic Toslink rather than glass. They offer a rationale here:

    I'd be inclined to trust them.

    glass v plastic is one of the enduring audiophile truism myths...like switched v linear power supplies.

    Life isn't full of absolutes. I think you should just buy a good quality plastic and enjoy it.

    Of coure we all know that coax is better anyway
    You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
