"The Dharma includes a dynamic driver for the bass and midrange, and an (self-polarizing) electrostatic tweeter for everything above 10Khz...and the result is a headphone with a soundstage that’s wider than I thought possible. The best part…they don’t need an electrostatic amp to drive them. In fact, I powered them with my Astell & Kern DAP and got musically satisfying results at levels as loud as I cared to go!" – Lee Shelly, The Audio Traveler, 31/3/2015
