My suggestion about the possibly of joining a WiiM beta test for Tidal hi-res support was in response to Keith_W's query in post #3. Keith_W apparently has a WiiM Pro.
I don't. I am considering getting one. The reason is not because of Tidal, but because I want to use Idagio.
I have gone on a rant on ASR before about how streaming companies can not use their own apps to cast audio to computers. The only exceptions are Spotify and (maybe?) Apple Music, but even then only to Macs and not Windows PC's. BubbleUPNP mitigates this somewhat, but then BubbleUPNP has its own drawbacks. On my system, it is INCREDIBLY laggy, with a 3-4 second latency for even simple things like volume control. Not to mention it's a bit ugly, and when people come over, they can't figure out how to use it.
