Looking to pick up a DDL card sometime soon, need one with a Optical Out, and thats about the only limitation. I'm going to be using this solely for it's DDL to send out to my Astro Mixamp, so the cheaper the card the better. The cheapest I can seem to find that support DDL with an Optical out is about $60 - $70, found some with Coaxial outs around $30 that do DDL, but sadly I need that Optical out. Only real preference is a PCI-E 1x card, but thats simply because it would keep the interior of my case cleaner, normal PCI cards will be just fine. So hopefully someone out there might know of a bit cheaper DDL card than I can find.
