I've heard both. Personally, I didn't like the Mephisto. I thought it sounded too soft, too lush. It definetly didn't have the weight or focus of the Electrocompaniet. As far as detail, soundstage, and decay- it doesn't get much better this side of SACD than the Electro. Plus, it seems to be an open window to the delicacy and weight that well recorded music offers. If the recording isn't good however, don't fool yourself. You can only polish a turd so much. Save your bucks, get the EC and go for the upgrade as soon as you can afford it. You can thank me later.
