Hey guys. I recently picked up a pair of AKG K702's to use with my Grace M902. So far the sound is amazing with only one problem being sibilance in the vocals. I'm just wondering will this sibilance go away after burn in? How long is the burn in? and is my Grace M902 built in AMP good enough to bring the AKG K702's to at least 90% of it's potential?
