Introducing the HIFIMAN EF400 Balanced Desktop DAC/AmplifierDesigned as both an homage to the acclaimed EF6 and a statement of modern audio technology, the fully balanced EF400 features our new low-energy, high sampling HIMALAYA R2R DAC, which features an array of highly accurate resistors that use a “ladder” method of conversion. This approach converts the digital signal with maximum accuracy and overall musicality. Signal-to-noise, total harmonic distortion, and energy consumption are at their musical and efficient best.
We have placed equal emphasis on performance, flexibility, and convenience when developing the EF400 DAC/amplifier. The fully balanced four-channel differential structure features our HIMALAYA DAC module, which supports the common PCM signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum 24Bit resolution. When combined with a buffer, active filter and Class AB amplifier that offers the fidelity of a Class A design and efficiency of Class B architecture, the HIMALAYA DAC raises the bar for desktop DAC/amplifier performance under $600.
The compact physical dimensions of the EF400 contradict its substantial output. Measuring 9.5” D x 9” W x 2.5” H, the EF400 requires the bare minimum of desktop or rack space. The front panel includes four balanced outputs – 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, XLR four-pin balanced – in addition to a four-level function switch and volume control. The rear input panel includes jacks for USB-B and USB-C source connectors, in addition to dual (L/R) XLR three-pin full balanced line outputs, a rarity in products at this price point.
Signal to Noise Ratio: 118+/-3dB (A Weighted)
THD+N (line out) : Between 0.002% and 0.004%
Channel Separation: 125+/-3dB
Maximum Power Output: 4.4 WPC (Giving the EF400 the power to drive the majority of low-efficiency planar headphones, including HIFIMAN Electronics’ flagship model, Susvara)
The EF400 DAC/amplifier will be available in March at a suggested retail price of $599. It will be available from authorized HIFIMAN dealers and our online store, http://store.hifiman.com/.
