Sorry I'm confused. Amir's test says that the Diana V2 has a bass roll off and an uneven high end. When I listen to the V2 in comparison to hifiman Arya or the 1266, the V2 sounds a little warmer and a noticeable amount more bass than the Arya but not as much as the 1266. I realize that Amir only tested about 6 or 7 headphones with his new testing rig and hasn't tested the Arya but if the Arya is considered good from a performance standpoint than to my ears the V2 is better. So I'm not worried about a graph.
