AKG K550 or Soundmagic HP100 with dragonfly

I finally narrowed down my choice to between these two to use with dragonfly but can't decide which one to go for hence need advice from someone who has experienced both , I will be using it with audioquest dragonfly and like to listen to all sort of music my key requirements are treble should be sweet but not bright or harsh and bass should be tight and punchy but not boomy and should not overwhelm the midrange , should be able to produce vocals specially female with authority and not shielded behind music.

Dale has recomeded HP100 but hasn't had any experience comparing it with AKG 550 so looking for someone who has experienced both and can highlight key differeces, I will be buyine one for a long time hence been bit stubborn to collect as much feedback as possible as I dont have option to compare the two. Thanks.
