There are multiple ways: Apple Airplay, Google Cast, UNPN. It all depends on your preferences/needs.
Apple Airplay
According to Wikipedia: “AirPlay is a proprietary protocol stack/suite developed by Apple Inc. that allows wireless streaming between devices of audio, video, device screens, and photos, together with related metadata.”.
As outlined here playing hires audio through Airplay has some limitation.
Google Cast / Chromecast
According to Wikipedia: “Google Cast, branded for consumer devices as Chromecast built-in,[1] is a proprietary protocol developed by Google for initiating and controlling playback of Internet-streamed audio/video content on a compatible device.”
According to this Google Chromecast help article support for hi res audio is limited to 96KHz/24-bit.
If you’re concerned about what Google knows about your play history, tracks and albums then I would not recommend to use this option. If you do not care then you can use it. Please note some configuration is required. If you do not reconfigure Google Cast after an firmware upgrade then you won’t be able to cast to the SA30 through Google Cast. Refer to the next article how to reconfigure Google Cast.
UNPN
I prefer this option because it supports hires audio and does not expose any meta data.
