Sell your grandmother and buy some Wilson Audio Sophia's.
You might even find some 2nd hand or ex-demo since they have been superceded by the series 2. They will do everything you want of them and more, great at low and high listening levels. Awesome with movies (even as a 2 channel arrangement). I think you'll save money in the long run as they'll satisfy your every audiophillic craving for detail, dynamic slam, with a sweet treble that you won't find tireing.
