Knowing that the new models are completely redesigned (from dual-sided magnet to 'advanced' single-sided), I find it hard to believe that there was no significant change in sound. Either bad or good there should be a noticeable change in SQ from the previous models instead of just staying almost the same. I find it odd for the sound to almost not change at all when there is a complete redesign done.
I would have to agree, unless the goal was to sound exactly the same, and there wouldn't be much point to that unless just lighter was the goal. Time will tell. I look forward to hearing them.
