Help with streamer software

I ordered a PS Audio streamer, the AirLens, due here this week. PS Audio does not have an app for their streamer, and I am not interested in using Roon. I found a full-featured app called JPlay that works very well for streaming Qobuz to my current Lumin streamer.

My problem is that I listen to a lot of internet radio, and that is not supported by JPlay. TuneIn and other radio apps that I am aware of do not stream directly to higher-end devices. I know I can stream to my ipad and bump that over to the streamer but the quality problems are well known.

Does anyone know of a radio app for iOS that will stream directly to a higher-end DNLA / UPnP streamer? Or is there another way to solve this without getting into the Roon world?

Thanks in advance.
