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.
