Tidal WiFi not as good as cd

Hi all,

Trying out tidal hifi and noticed that the same music airplayed to my dac is not as good as my CD ripped to the computer and airplayed to the same dac. Almost sounds like a lossy file. Am I doing something wrong or is this what is to be expected because of streaming. Not exactly sure what Roon is but heard it should make tidal streams better. If so, would it still be worse than ripped CDs?
