I've tested the LCD2C with my WM1Z, seemed to have enough power, they sounded pretty good. My reference headphones are Focal Clear, personally I think they are a better headphone, sound and comfort. Of course this is my preference so....I'd recommend giving the Focal range a listen if possible. The Massdrop Elex is pretty much the Clear model but at have the price, and The Elear model sounds almost identical to both models with the Clear pads. The Utopia models are also fantastic, but too much for me to spend and didn't think the sound upgrade was justifiable. Cheers!
