compare Meze Empyrean with Focal Stellia

Looking to upgrade my headphones. Pretty much tied to these two as options. The Meze is open and I'd prefer closed however I'm intrigued by the appearance and the tech innovation. The Focal is closed, which I prefer, and I've heard some opinions that it's particularly good for classical--which is 80% of what I listen to. 

I'll be listening though my phone, but with a dragonfly red DAC, and directly from my Hegel Rost integrated.

I like clarity, accuracy, a good soundstage. 

Thanks for input.
