I've got the P-11A. Did my first mixes on them yesterday. It's too early for a full report but so far I'm in hog heaven. Didn't have to "learn" these monitors at all. I just trusted them and mixed till it sounded great and they have translated perfectly to everything so far. It's so great to twist a knob and trust that what you hear is what you'll get. They can't take a lot of volume but I prefer to mix at low levels so that's no problem for me.
