Depending on your listening habits you may find there is not enough gain for the AKG 701/702's, and they do like lots of current to sound their best. Years ago I remember a number of headfiers configuring the DAC1's balanced outputs with balanced out to a stereo female 1/4" adapter and it worked extremely well with the Sennheiser 600/650's and AKG 501/701's.
