Massive power, superior sound

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

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

Fully balanced 

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

The four-channel fully-differential amplifier circuit features a maximum output of 10.7 Vrms on a 36Ω resistor equivalent load. The result: fully balanced output beyond compare. 

The connection king

Boasting nine inputs and outputs, the EF400 can run your whole collection of headphones or pass along amp duties to another taker.

Making gains

The EF400 features a 4-level function switch for selecting High Gain NOS, High Gain OS, Low Gain OS, or Low Gain OS. Whether you prefer oversampling or non-oversampling with your R2R DAC, the EF400 has you covered.
