Well I finally got around to listening to some of the dub track for episode one. I'm not highly impressed, but then I didn't expect to be. Was most impressed by Misuzu's VA, least by Yukito's actually - I disliked the 'let's have attitude!' style that the dub script seems to have given him. That said, the substream was very good, and was highly enjoyable, and the dub itself wasn't terrible in any aspect. ADV have done a thoroughly decent job for both tracks, as far as I can tell. Well done, evil licensing company.
