I currently have a Dennon 2803 receiver and eveything is connected up via the SPDIF output (optical) from the onboard NForce sound. This is working great except one minor niggle in that the optical connector on the pc is not good and the cable has a habbit of jumping out. From my previous AV setup I used coax digital connections and I prefer them just becase they feel more solid. Other than changing between optical and coax digital connections, is there any point in actually getting a soundcard if all the decoding is done by the amp anyway ??
