How would you compare the Audeze LCD 2 against the Focal Elex headphones?They are both excellent headphones. The LCD 2 is going to have more bass and be a little more "rolled off" at the high end (the Audeze "house sound"). They still provide good detail and excel in the mid-range. The Elex is going to be a little more neutral throughout the frequency range and I find them more comfortable to wear. Which isn't to say that the Elex lack bass or that the LCD 2 is uncomfortable. The Elex has good bass response and maybe a little more "realistic". One of the things I like about Audeze is they come with really nice earpads and are comfortable from that standpoint, but they are a little on the heavy side.
I suggest checking out Headfi and Innerfidelity for in-depth reviews of both.
