HiFiMAN EF400 DAC & Amplifier – Addicted To Audio

In 2012, Dr. Fang Bian and his team at HIFIMAN introduced the EF6, the legendary desktop DAC/amplifier that delivers gobs of power for a wide, detailed soundstage. Ten 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 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 36, resistor equivalent load. The result: fully balanced output that is beyond compare.
