@DrkLord this might be helpful. Personally have the HE400i which I got for 11k after card discounts and couldn't be happier - especially with eq'ing! Use the eq only for music tho; prefer their stock sound signature for movies.As Nitendra said, they all sound very similar. Deva has a touch more midbass and warmer sounding. The mids in these headphones are not as forward as in Sennheiser HD598/ 599 though specially the male vocals.
I would have bought the cheapest one available among the 400i/ SE/ Deva ( as I have tried them all)
