If you must have wireless, a cost-effective solution is to buy a used/refurbished Apple Airport Express on eBay. You plug it into a power receptacle near your receiver and connect the two using either an analog or digital audio cable. iTunes (or foobar2000 with Airplay plugin) can be used to manage your library and send music to the Airport Express. You can download an app and control everything from your tablet or phone. An added benefit is that you get a wireless network range expander in the under flat.
