The ML Summits require a decent break-in period. All stats do, but Summits even more because of the higher membrane tension resulting from new manufacturing techniques. So they probably don't sound all that great "out of the box."
The ones I heard at CES sounded amazing and had a huge soundstage -- however -- The rep did say (when I asked) that they had only 3 demo pair, and these had plenty of mileage on them.
