I got rid of my 950's unfortunately. before I had a chance to run them on a STAX amp. Had I known of that little trick at the time I would still have them. The word I used to describe the 950 was "polite" They never jump out at you with an unexpected frequency "highlight" or transient anomaly.
Working up a set of T20's now so I am very interested in the MD sign. Imaging is good the depth lacking so far. The MD T50 may just turn out to be the way to go for me here. (Until I come by a spare 700 bucks for a new 950 rig).
With lighter music, I vastly prefer the ESP950 to the MD. They have a sense of air that I've not heard captured by a non-'stat or a closed can before. However, they don't handle really heavy stuff quite as well, and since almost all of my repertoire is rock I tend toward the MD on most occasions.
