Actually, Cavalli has said the LC will do 2.8W continuous into 50ohms: http://www.head-fi.org/t/761088/new-cavalli-audios-liquid-carbon-a-599-cavalli-amp/1485#post_11607837 This is a bit OT, so sorry. Still burning in my Liquid Carbon, but here is what I've heard so far: I've been mostly listening to HE-6s because, even though they were used, PO said they had about 200 hours on them, so I want to make sure they are broken in along with the LC. With the LC, they really can sound good. That is with Mojo at 3v line out and 3x gain with volume between 11:30 and 2:30 for fairly robust listening, which I was doing a lot of just now to prove/disprove that the LC could drive them. It sounds sweet at 11 for background listening, to me, without a loss of dynamics. And, let me add, I was comparing the LC to the HE-6s driven by my Odyssey Stratos Stereo Extreme amp with the Hifiman speaker adapter. This is a 70 lb., 150 w/channel amp with 2 x 400 VA transformers and 180,000 microF of capacitance. It has the goods to drive the HE-6 with authority, and it sounds fantastic, but is inconvenient for me to use it as the primary headphone amp. I would say it will require more listening, and to be fair, I have to take the preamp out of the chain or add it between the Mojo and LC for complete comparison, but aside from a slightly different sound sig (not to far off each other, actually), the LC can deliver 95-98% of the authority the Stratos does, and that is even debatable depending on how the ultimate sound sig comparison comes out after burning in and more listening.
