All of these are great options. Have you heard any of them? The Diana is great but overpriced imho -- the other two are competitive at almost half the price. Between the Arya and the Auteur, I think it's really just a matter of preference. (I've auditioned both a couple times, but haven't owned either, so take these impressions for what they are -- impressions.) The Arya will sound more open and "ethereal" than the Auteur, and it has better forward-soundstage depth capabilities. It's a little brighter (some people say there's a mild peak at 5k, it wasn't super noticeable to me), a little more resolving, and has faster transient response. The Auteur is a little "denser" and warmer, it has a richer and more organic sound than the Arya. Don't get me wrong, the Auteur isn't overly warm or dark, it's actually quite neutral, especially compared to some of ZMF's other stuff. But I think it's more romantic-sounding and fuller than the Arya, and the timbre on the Auteur just struck me as being so natural and "correct." I found both headphones to be quite comfortable, but I'd give the edge to the Arya because it's lighter. That lightness comes at a cost, though -- in terms of perceived build quality, fit and finish, the Auteur easily outclasses the Arya. I think ultimately the Arya is a little more versatile if you listen to a wide variety of genres, and it's the better technical performer, but from what you've described in terms of your listening habits, the Auteur might be right up your alley.
