So I fell in love the the Senny HD650 + Crack combo, and i think i'll keep the 650's until i can afford some 800's, i was fortunate enough to listen to them paired at a friends place, and i can definitely say they're my end-game (for now).
 
I was wondering what would be a good pairing of closed back cans for this amp? I've heard good things about both the DT770 and DT1770, but not much from anything else, any recommendations would be welcome!
