So a bit more feedback after listening to this all night. This is a bright amp. My LCD-2's have actually been a bit sibilant. I am running the setup off the ifi BL DAC which is fairly neutral in my opinion. The sound stage is great, but I am not sure this amp would be acceptable with anything but a dark headphone. I will continue to update once the amp burns in all the way, but first impressions are a bit bright.
