Description image for Hifiman EF400 R2R USB DAC High-Power Balanced Headphone Amplifier

4.4W Per Channel Balance Output

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 36Ω resistor equivalent load. The result: fully balanced output that is beyond compare
