thank you very much for your answer.
Simply said, I replaced a fm-tuner with the Omnia WR-1 in a very traditional "vintage" (Luxman, JBL) set up (preamp, poweramp, speakers). I remote control the Omnia via my iPhone. This setup works quite fine. I have the Spotify-app and the Qobuz-HiRes-App on the phone.
Furthermore I'd like to connect a laptop to the Omnia, because the computer-app of the Qobuz-service allows you to make sure that you really listen to HiRes-files. The Omnia won't show the resolution-data in its display. It shows which song is playing and that's that.
Hence my question in my first post.
Thank you once again.
