I was a big MOG fan, and I switched over to Beats. The sound quality is noticeably worse than MOG. It's still good, but it is an obvious downgrade. I just signed up yesterday for the free trial of qobuz. The sound quality is superb. You can even stream hi-res tracks, which sound incredible. The only drawbacks so far are (1) it's all in French (although google translates it on the fly pretty well, (2) the catalog is much more limited than MOG or Beats - at least for the music I listen to -- but it's still very good, and (3) there seem to be some glitches with searching and with streaming in the dedicated app. Still, I highly recommend trying it out.
In the meantime, people have been complaining to Beats, so maybe they will improve their service as well.
