Integreating the Powernode 2 into the BlueOS ecosystem

I purchased a Powernode 2 two years ago and it has been great, however I now want to share my music with a Marantz SR7005 receiver and have come to find out the output options on a Powernode 2 are close to nil.  If I purchased a new Powernode and connected the Powernode 2 to the receiver using the speaker outputs, could I then select music on the Powernode and have it play through the Powernode 2?

Thanks
