MJ1 and PMx2 have really great synergy! I highly recommend the MJ1 over the Jot 2. The Ragnarock 1 and PMx2 are a bit of a better match, but really you are in for a treat! You will have plenty of volume control, the extra power from the MJ1 gives great control and really wakes up the PMx2 driver. It has a tendency to be overly smooth when not given enough juice. The MJ1 has great dynamics and driver control.
