I’ve been running Zu Omen DWs for about 2yrs. Awesome value. Great build quality. Run them with a yaqin MC-13s (chfi push pull based on old Hafler circuit) running 38w into 8ohms. DWs are 98db efficient. My power meter rarely steps out beyond 10w. Great imaging, good soundstage, awesome dynamics for their price.
About 2 weeks ago I pulled the trigger on a set of Druid MkIV. Same front end. I’m still setting them up. Not as simple as the DWs. So far, I’m wildly impressed, and they keep getting better everyday. 101dB efficient. Crazy dynamics. Everything is just bigger and more lifelike. That said, I am contemplating a change in amp - mostly just to see what SETs or Class A SS has to offer.
Im sold on the high efficiency crossover less design of Zu and others mentioned in this thread. Haven’t heard or seen DeVore but I can say for certain that Tekton seems to puts the money into the drivers and less into the cabinet and finish. I wish Tekton would up the build game because they sound marvelous (and are made right there in UT).
