Chord Electronics Mojo 2 DAC and Headphone Amplifier
Chord Electronics Mojo 2 DAC and Headphone Amplifier
The Chord Electronics Mojo 2 supersedes the world-renowned Mojo DAC/headphone amplifier and introduces an impressive list of new features. The British designed and built Mojo 2 is the most advanced portable DAC and headphone amplifier in the world today. Entirely engineered around a powerful, custom-coded FPGA processor, Mojo 2 benefits from several unique technologies. Central to the new Mojo 2 is the world’s first lossless DSP, an advanced ‘digital tone control’ without any degradation in sound quality. The ‘UHD DSP’ gives Mojo 2 unrivalled compatibility with today’s wide-ranging headphones, plus unparalleled flexibility with partnering equipment.
A further key feature is the new menu system, navigated via the new (fourth) control sphere, bringing mute, crossfeed, button-lock and tone control adjustment. Mojo 2 offers greatly improved battery management, with faster charging rates, a huge 75 % reduction in power loss, plus a 9 % capacity gain. A new USB-C data input adds greater flexibility, transparency has been greatly boosted, thanks to an improved noise-shaper, lower distortion and greater neutrality, plus Mojo 2 can even be taken wireless with the Poly streamer/server. Handmade in the UK with a robust CNC-milled aircraft-grade aluminium chassis, Mojo 2 offers unrivalled performance, class-leading sound and peerless build quality
