[linds_15]

anyone know what the comparisons are bwtween the old s<v<w<z<xbr to the new series which is the ex and nx?

also the only difference i notice between the ex500 and the ex 700 is the bravia engine, the 500 being a bravia engine 2 and the 700 a bravia engine 3, whats the differerence between the 2 engines?

thanks again for all the help
