Wirelessly it seems like you are limited to Airplay, but it looks like it will play music from a network DLNA server, and worth trying with a USB cable.
It also supports Roon and Tidal.
Wired connection from Iphone to processor
Hi, Wonder if anyone can give me guidance on how to get lossless Apple music from an iphone to a Lyngdorf MP40 processor to listen to music on my home theater Revel f228, Revel Voice, Revel embrace speakers. I listen to music mostly in stereo but also surround. If it's not possible with an iphone is there another way? Appreciate any thoughts. Thanks
