Logitech Z-640 Speaker Connection

[InternetOwl]

Can anyone out there tell me if the Z-640 5.1 speakers from Logitech can be hooked out to the Digital Coax S/PDIF port on my A7N8X Deluxe board so I can finally bypass that awful Realtek codec? In other words, do the Z-640 speakers come with a standard coax cable?

The ones I got have analog connectors - front, rear, and center/subwoofer plugs. I think the z-680's have the digital connector. But they're a good bit more expensive than the z-640's.
