I own the BIC DV62 speakers. They're very good for the price. I would not recommend the DV52s, as they have much less bass response, and a cheaper, smaller tweeter. As far as the mod goes, it helps reduce the brightness that these speakers have. You may like the brightness, as you are a Klipsch fan.
But ah yes, the Magnepan MMG speakers. They'll be excellent with music, though you would need a hefty integrated amp to drive them.
