I'm satisfied. 99% bluetooth clean stream for me on new 2.0 firmware, better than 90% from past firmware. I can get 100% if I don't move, touch or mess with my smartphone (the amplifi remote controller app). My device being HTC One Max Android Verizon, and sometimes Nexus 7 tablet.
Tips: keep the device as close to the amplifi (mine is model 150) as possible, find the clearest/fastest wifi channel (mine is 5GHz Apple Time Capsule), keep the device plugged in (for best CPU and wifi performance, disables most power saving and makes it fast as possible), most importantly make the hand-horn (index finger up, middle fingers down, pinky up, thumb in) the standard rock 'n' roll salute!
