I'm tired of using my laptop and external HD as a digital music player in my audio systems. All I listen to is 2 channel stereo. Does anyone manufacture a decent (near audiophile) unit that handles all file formats (VLC player is my favorite) and would ideally use an external HD (collection is > 500 GB). Prefer an internal DAC for portability even if less than ideal. I'm tempted to build another small computer but don't really need much of a display and don't know of any options other than small flatscreens. Thanks, I'm hoping I can buy something for $200-400.
