I recently set up a couple home systems, and I realized how fine Dolby Digital sounds. I'd like to get this experience with games on my PS2 (and the upcoming consoles, if they hopefully support optical cables *crosses fingers*), but I noticed some places sell optical cables for quite a hefty amount. If the cable is worth the purchase and will last me long (for example, even for when the new systems come out), then I'm willing to shell out something like 30 dollars for it. That's just a guesstimate. I don't know how much optical cables should cost, I'm asking someone here. Please tell me. I'd like to get one that's worth it. Thanks.
