If you follow Jason and Mike's posts Schiit has developed their own USB receiver they call Unison USB which is in beta testing now supposedly will be introduced later this year or early 2020, so you would need to send in your Yggy for a new USB board unless you are comfortable replacing it yourself.
I had both Tidal and Qobuz and recently dropped Tidal. No use for MQA and there is plenty of 24/96 and 24/192 content on Qobuz. One downside to Qobuz is they still have a slightly buggy UI while Tidal is trouble free. I sorted that by buying the Audirvana+ player which works just fine with either Tidal or Qobuz and also lets you use VST plugins and upsampling.
