How is the soundstaging better - elaborate?
I have the same headphones driven by Roc. I find LCD-2 (rev. 1) more detailed and with all the bass one (no-basshead) can hope for. HE-500 has the edge only in soundstaging.
(HE-500 with HE-6 OCC cable; LCD-2 with Norse Audio 8-wire OCC cable; both differentially driven)
