I'm looking to upgrade my pro 550's, about 50% music and 50% gaming use and I honestly liked these pro 550's. they are my first real headphone and im looking for a newer headphone for the same uses, i've been eyeing maybe a used dt990 pro 600ohm?
 
Any reccomendations (i like the bass on the pro 550's, how does it compare to say.. the q701?)
 
 
Dac is xonar DX
Amp is Schiit Magni.
