Thanks for that mimi review Slim. I already have an electrostatic headphone but it is currently paired with the cheapest Amp I could get for it. I am kicking around the idea of building my own Amp with the help of my friend who has already built a few varieties of KG amps. I would be interested to know how close this ifi combination can get to theses heavyweights. If it gets close enough, it would be nice to have as an all in one since I already know that I like the ifi sound (with the BL).
