I have been a member of MOG for >6 months. The sound quality from MOG streaming or downloads (320 kbs) is magnificent. I have even done side by side comparisons playing the same song from my iTunes library (Apple Lossless from CD rips 16/44) and MOG sounds better, not sure why but it does sound more clear and more musical in both headphones and Audioengine A2 speakers.
I tested Rdio and Spotify with MOG, and in my experience MOG has by far the best sound and equal catalogue of music. I am not sure why Spotify is so well known but MOG is still unknown by most, but they are the best and the have fantastic apps for the computer, the iPhone and the iPad.
Totally Agree. I love MOG. Best audio Quality. Not s fast as Spotify, and no Gapless, but I still Chose MOG because of the greatest sound quality. Spotify claims to stream at 320, but the sound is just not there
