I would take your JM Labs over any of the newer speakers you list.
"Looking for a wide and deep sound stage with a depth of detail from that speaker."
If that's your goal, my first choice would be a pair of Vandersteen 2's, but I think your room may be too small for them. A small pair of Audio Physic or Thiel should work very well for you. Or, if you like your current speakers, maybe stay with that brand.
