I wasnt blown away by the sound stage of the LCD-2,so take my comments with a few grains of salt.
The Blackwood is closed,so inherently the stage will be compromised to a certain extent.On some tracks I am surprised by its width,and then on other tracks its smaller than I wouldve thought. Other times Ive heard the stage being pushed R/L vs. the holographic presentation you mentioned you like on your Audeze.
I havent heard the Audeze X,so I cant comment.
In summary for a closed back its stage is good,but if staging is a priority,then I would suggest an open back.
