I got mine,and I can tell you it is great keyboard...It is almost better than pa800.I like design of this keyboard..And black is also plus.I have not tried onboard speakers.I just plug it in my PA.It reads samples from pa2x and pa800.It doesn't read pa3 samples.Probably because pa3 compresses it.It reads styles from pa3 which is a big plus.I loaded some new drukits in ram and it sounds like live band sounds..
I love it.
