If it is going to be a fair battle it would need to be the DT-1990 but even still I think the XS are better sonically. I think the LCD-X may be your best bet instead of the 2 due to it's wood cups. If you mean the LCD-2C then that would be another good one but if you can save a little more I think the X is the way to go. Just so you know, while I prefer it, the sound of Audeze is much wamer/darker than Hifiman. So they have more slam to the bass but no where near the sound stage.
