I heard the Wolcott Omnisphere speaker at CES, and did not like it. Understand though, I have never heard any brand of Omni spherical speaker that impressed me. Perhaps it's just my personal way of listening. Although CES is a terrible place for the only listening to have occurred, but I have heard good sound from other products at this show. Last, there is a high and low toggle switch, as well as a rotary knob on the rear of the Wolcott amps. The user may adjust the damping to whatever suits the speaker, room and listeners taste. A nice feature.
