My Yamaha rx v477 has a network connection on the back panel. I installed Yamaha app for Android and it finds the receiver. If i play any music file it plays through the Yamaha receiver. maybe you need the Marantz app to do so.
Keep in mind the performance of wireless adapters differs based on various factors in your setup so it is not an optimal alternative for a wired connection. If you do get one of these and use, please post your feedback that might help others who may look for a similar solution.
