Congrats on the Yggi!
I have a cheaper dac and still I don't think the sound is nearly as good with my phone as a streamer as it is with a computer. You might want to order an Allo or something else pretty quickly.
You had an earlier question about software and I just use Volumio on my RPi and controls that from any phone. We mostly streams Spotify on it by just choosing "Stream to device" and choose the RPi but I store flac files on it also. If you want to use Tidal or Qobuz you probably need a subscription from Volumio. They are around €29 per year or less than €3 per month if you pay for a year. You might also be able to use Roon but I have not tried that.
