I would recommend a Raspberry pi + Volumio software for a much cheaper alternative.
If you already have a separate DAC with a USB port, you can add a streamer to your system by installing the (free) volumio software on a raspberry pi. Even with power supply, SD card, and a case, this will be around £50. You can then control the volumio software from a web browser or via the (free) volumio app on a smart phone/tablet.
There are cards you can add (which require slightly larger cases) that will do the digital to analogue conversion or provide coaxial/optical connections.
Next to no expertise is required for this. Instructions on how to set this up are on the volumio website and it will probably take you longer to order the raspberry pi, SD card, and find a case to your taste than to get this working.
Would folks know of any digital network player similar to Denon Dnp800NE feature set that has analog volume pot ie with a traditional volume analog pot ?
Yamaha WXC 50 and CA CXN are possibilities. Any other ?
