Ultra Airplay

Buy an AirPort Express. Make sure it’s the A1392 model. They were designed as Apple’s version of a mesh network and have Airplay 2. I found one online years ago for $30 and used it to stream to an older amp using its line out to rca input on the amp. Easy to setup and has been 100% reliable for me.
I’ve now connected it to my Ultra via RCA input, and output via the Ultra to my simple Primare I32 amp. Works perfect.

I’ll give you an even better idea: instead of using RCA, use the Express’ built-in optical output. The mini jack port is dual function: it also accepts mini-Toslink. That way you use the (probably much much better) DAC of the Ultra.
