Wayne,
You don't necessarily need a network player if you can connect from PC/Mac to DAC via a USB interface and are happy with the sound and control features.
The advantage of a network player device like a Squeezebox or Soundbridge is it connects to a network like a computer but is designed specifically as a cost effective but quality audio component and all that goes along with that compared to a general purpose computer.
It takes some guesswork out of which computers might sound good and which will not since that is what these devices are designed for.
They also provide useful control features that will vary from device to device like a remote control, random playback mode, etc.
