I posted our CES configuration over here (Post #68) -
https://forums.evga.com/FindPost/3023268 Powered speakers are recommended, unless you have or plan to buy a dedicated pre-amp for them. In our case the Edifier speakers came with basic 3.5mm to RCA cables and RCA to RCA cables, and the speakers were the type to run the PC cable into the powered speaker (the right speaker), and run speaker wire (included with the speakers) over to the non-powered speaker (left speaker). For the center/sub, we used a 3.5mm splitter with a 3.5mm to RCA cable for both the powered speaker and Sub (I'm sure there's a better way, though).
