Up until a few months ago, the Z-680 was Logitech's top of the line computer speakers. That title now belongs to their new Z-5500 Digital. However, just because the Z-680 is not longer top of the hill doesn't mean the speakers are no good - far from it. The Z-680 is still among the best computer speakers money can buy. And thanks the fact that it's no longer top of the line, these speakers have become a super great buy.
