KEF LS50W 2 - 110v vs 220v

Hey,
First time poster.  I live in the US but am currently in the EU visiting family.  Due to favorable exchange rates, I can get the KEFs at a significant discount to US retail, but am concerned about the 110v vs 220v power standards.  Is there any risk buying an EU model and just replacing the power cords with a standard three-pronged US power cord or using a converter?

Thanks!
