As opposed to the hype surrounding the MD which have been mentioned to be giant killers a HELL OF A LOT here? Lol. It's been mentioned enough times that the K702 65 is for those who wanted more bass, warmer, less fatigue from the other 70x variants. To lots of people, that IS an improvement.
I personall never liked the other versions for music use. With the 65, the musicality was quite improved, and made them considerably more enjoyable to me. Is it as technical and analytical as the ones before it? No. But I'm looking to enjoy music, not dissect it.
As for things it did better than the LCD2, it's no mystery. It's more airy, spacious, not as warm, making it more balanced, IMHO. I have let a few friends try both out side by side, and they came out more impressed with the K702 65. This includes the guy that came over to my house and bought the 702 65 on the spot after demoing both. If I had thrown the MD in the mix... it would have been left behind.
