LZ-A2s's quality is the same as A2 with a bit more warmth, and personally, I think the vocal position makes more sense (A2 is like at the back of your of brain). I've been trying to compare the two, but it's not easy to nail down the subtle differences except what I've just said. LZ-A4 won't come out so soon. I'm also listening to the prototype. Lovely female vocal.
