Simplified Audio, Reimagined

We’ve reimagined our flagship amp+DAC to create a listening experience you will notice and appreciate. Element III operates on our second-generation XMOS hardware and firmware, blissfully integrated with a custom encoder. You’ll hear perfect channel balance down to the black noise floor. Automatic gain helps you focus on listening rather than button pressing, and an auto-vanishing display presents the essentials while you toggle between USB and Optical inputs and headphone or preamp outputs. Element III MK2 upgrades the iconic knob with a discrete, optical encoder for unmatched feel. And we’ve added a 2-band EQ to adjust bass and treble to your taste, along with DSD support, selectable DAC filters, and more. Element III MK2 is designed and built in the USA.
