HiFiMAN introduces 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 desktop DAC/Amp solution, with a compact footprint and price to match, but with sonics that outperform products many times its size. Power Output: 4.4W per channel. Is there a better way to drive a planar-magnetic HiFiMAN Headphone?

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 ohm resistor equivalent load. The result: fully balanced output that is beyond compare.
