I sold my K702's a long time ago, when the LCD-2s came out and I purchased them. I have since missed its sound signature.
The Q701's do not disappoint! And to me are extremely comfortably light. I was expecting them to sound too sterile with the sabre dac but its actually really damn good. The amp in the Compass 2 doesn't give these justice, the M-Stage is a better amp for these by a long shot.
I have a very fond memory of these line of headphones~ And if the Q701's sound slightly different than the 702's, then that difference is going to be quite slight for most ears. They have the unique day 0 qualities~ As they burn in I expect the treble bite to mellow out just a tinge by many hours of use.
What kills me is some people think these cans have like no punch to the the lower registers, but that is far from the truth. It is just very clean and well extended~
