Does HD800S with EQ come any close to HE1000SE?

This is a purchasing decision. Money isn't that big of a concern for me but I do not get to audition these headphones in my local area with EQ so I ask the question.

I think EQ isn't factored in to price proposition in most discussions so pricing of headphones mostly boils down to how good it is out of the box. HE1000SE is good out of the box. But if I could get HD800S and EQ the heck out of it, how close am I getting to HE1000SE?
