These were taken for Ω's upcoming review of this remarkable portable headphone amplifier that has me running back and forth between it, the ALO Audio Rx MKIII-B+, and the Vorzüge PURE II. The short: DUET is a marvel of control, speed, and good liquidy sound.

NOTE: Somehow, this advertising photographer messed up whilst shooting for review. His Sony a7r somehow crept into JPEG mode and got locked into Kelvin 5300 white balance before he packed his studio up for the Headphone Book 2014 shoot. Good enough for a review, but bugger that.
