I dont know if this is relevant. But I will inform that Solo is Working over Wi-Fi from the cheap Jriver 28 with Upnp server of Jriver on windows 10 I use the cheap Jremote on ipad10 with all albumart to control. Also my Cheap Sony Ubp x700 uhd Blu-ray works flawlessly with jriver 24 bit audiophile Dac server of Jriver but no album art, and Windows media player with the generic server of Jriver, but you need to load the albums to play.
Very nice sound quality, also the cheap Poweramp on my Sony Xperia 1iii phone works over chromecast Limit 24 bit 192. And of course Bluetooth sbc on android and aac on Apple. And Spotify Connect and tidal hifi over chrome cast, qobuz also.
I hope this is useful information.
