BAT VK-300x Reviews?

Someone suggested to me this integrated in another thread. My interest is piqued, though I have never thought much of integrateds unless one was on a tight money/space budget or for a second system. Anyone run one of these through the paces? I am concerned regarding the "modular" approach where you can add-on super tubes stage, phono stage, remote, etc. Love to hear practical input regarding this piece.
