I used MIT Terminator 2's for a long time. They are two steps above the 4's and the top of that particular line of MIT products. I also have extensive experience with 4S11. 4S11 is a much better product. Much better bass, much more spatial. The MIT cable's I find to be fatiguing. Of course the 4S11 is a fraction of the cost. At their cost you can't go wrong if you want to try them.
