The problem is the av reciever most of those units will not allow you to alter the streaming input.
Here is what I mean in a Pioneer receiver you push a button called network and boom you have the network streaming functions, you can't go into the receiver and assign that source button with a different digital or analog input to allow the processing to come from a different device.
The solution is to go to a high end streamer/dac/amp with app such as Naim or Linn and there are many others.
These devices hook up to the network and can pull UPnp/DLNA files from the Network and play and control them.
If you are trying to incorporate these devices into a theater setup it can be done with some creative hardware and custom remotes.
