I find that the thing that determines the midrange of a headphone is the amp that is powering the headphone more so than the headphone itself.
Usually recessed mids can be attributed to a headphone being inadequately amp'ed. It may still go fairly loud, but the mids sound somewhat withdrawn.
Sound Quest you are right. The amp/dac brought the mids forward which I really like. Also the sound stage is a bit wider too. If I have to nick pic I wish the higher frequencies were a bit crisper. But I am really happy with the combination.
