Anilnediyara,
i asked same question as you do (i looked for a 581SE at the begining). I got this answer, the 381 is tuned a bit differently than 581. 581 is a bit sharper and 381 is a fair bit smoother. I got the same response for a compairson of 781 and S7i also. I believe you can contact Wadia directly and ask for a serious opinion about it.
