Thanks to all for the very helpful info. I looked at the VMPS website; it appears not to have been updated since 2002. Their phone number still works, so I left a message.
I will check out the other suggested brands as well.
How important is the phase control? What changes do you hear as you adjust from 0 to 180 (or whatever), and how noticeable are those changes? Can the same changes be achieved by adjusting sub placement?
