I have a Synology NAS and for years and years used Logitech Media Server (beta) to stream music to Raspberry PI DACs, SqueezeBox DACs, and AirPlay wireless speakers. Using LMS plugins you can stream Tidal, Qobuz, Sirus, Pandora, AirPlay, etc, and play DSD, FLAC. iTunes, MP3, and other files.
I now use Roon instead of LMS. If you care about MQA, the Node2 is probably a good choice. I use a Mytek Liberty DAC and an Innous Zenith MK2 for streaming/rendering everything. Before Roon, I tried the BluOS app but found it too limiting because, unlike Roon or LMS, you can't consolidate all music sources into one interface.
