HIFIMAN EF400 | Desktop DAC and Amp

Massive Power and Superior Sound from a Sleek and Stylish Chassis

In 2012, Dr. Fang Bian and his team at HIFIMAN introduced the EF6, the legendary desktop DAC/amplifier that delivered gobs of power for a wide, detailed soundstage.

Then years later, HIFIMAN is proud to introduce a new model, EF400 that incorporates the best of recently developed technologies, especially the company's advanced HIMALAYA R2R DAC. The EF400 is the modern desktop DAC/Amp solution, with a compact footprint and a price to match, but with sonics that outperform products many times its size.

Full Balance

The four-channel differential structure features a DAC, buffer, and active filter that add up to unbeatable fully balanced output for stunning performance from a Class AB DAC/amplifier.

The four-channel fully differential amplifier circuit features a maximum output of 10.7 Vrms (THD<1%) on a 36ohm resistor equivalent load. The result: fully balanced output that is beyond compare.
