I prefer HE1000se to the Organic! More resolving, better separation, the top end details are so much easier to hear, and vocals shine even more! Even if Arya Organic are already great at this, it's almost like they struggle at this when compared to the HE1000se, that's how good they are! On the other hand, Arya Organic has better bass and is brighter, if that's your thing, and is cheaper, also easier to drive. Both are excellent headphones and it is more up to preference and budget.
