You must be out of your mind if you think the Sierra's are anywhere near as good as the Pulsar's the drivers are top notch,and Jeff Josephs steep sloped crossover is the best untilazation I've heard out of the SEAS metal drivers.At last years RMAF the Pulsar along with the upper end Green Mountain monitors, Eosteric monitors,and the 1s playing in the Monarchy room for $2300 were the best monitors at the show.The best monitors I've still heard to date are the Dynaudio C1 on multiple occations to,i dont think the Pulsar is at that level though,But nothing I've never heard is including the new Focal Utopia monitors, Wilson Duette and the Maggico.
