I had an M&K MX-150 with VA Bach's and I too wanted a better sub for music. I just didn't have the crossover flexibility with the M&K. I picked up a Storm III and cannot say enough about how much of a difference it made. I always heard bass is supposed to be non-directional, or is it omni-directional, but with the M&K's high xover I could sense where it was coming from, not with the REL, I feel the kick and the bass sounds like it's coming from right in front of me, which it isn't it's in the same corner where the M&K was.
Can't comment on the differences between the two subs. I'm more than happy with the Storm. I guess it would depend on how much power you really need to match your room and main amp/speakers.
Call Sumiko since they import both brands. That is the same advice someone gave me a few months back. I took it and they answered all my questions even knowing I bought the sub second hand.
Since this is an HT forum, it rocks for movies too!
