At Sony's web site they describe the KP-57HW40 as having a Microfocusâ„¢ CRT and Microfocusâ„¢ Lense System. For the KP-57XBR2 they list a Hi Definition Microfocusâ„¢ CRT and Multi-Element Microfocusâ„¢ Lense System. Does anyone know if both these sets are actually using the same CRTs and lenses, or is the XBR indeed using superior elements. I've seen both sets side by side and they are very, very close. Could it be that Sony is embellishing their description of their XBRs to just pump them up a little (for the extra dough you pay)? Thanks.
