Sure! For most of my desktop analysis of the amp section I used the Sennheiser HD800 and Sony MDR-7506 headphones. I tested it in portable environments with the Mee a151p, Oppo PM-3, and (forgive me for I have sinned) Apple earpods. I tested the line out directly into JBL lsr305s (paired with a SVS SB-1000), Eve sc207s, and Yamaha NS10s. I also tested the line out into a Schiit Asgard, Schiit Valhalla, and an Allen & Heath QU-16 Mixer.
