Depend in what is your definition of improve. To me, k702 lose the warmth and intimate vocals that i like so much about ad700. The added upper midrange emphasize doesn't help either.
But maybe you get more detail out of k702.
I see, that's good. Because if this sounds similar to th500rp (judging from looks), it is quite dissapointing.Thanks. I just realized that Ether is using entirely their own driver, i initially thought it's still using fostex driver.
