The Leviathan is still roughly 2-3 months out. As lovely as the WA5-LE is-it isn't really doing it for me soundwise. I do have an Eximus (3rd one lol) arriving tomorrow, should be interesting to see how that pairs with the Woo-my v800 has been excellent in the interim. I've honestly wanted this Luxman for a long while-but they rarely come up used. It's possibly the best ss amp one can get for the HD800-and that is my hope that it will work as an end game ss in that regard. The guy I bought it from prefers it with his HD800 more than the GSX, which isn't surprising, really. Supposed to be fantastic synergy there-can't wait to see how it shakes out.
On a somewhat ironic side note-I'm more of a black electronics fan myself-but the Woo, Eximus, and Luxman are all silver and are the best looking components I've owned (judging from P1u pics). Funny that.
