HiFiMAN EF400 Headphone Amplifier / DAC

HIFIMAN is a world-famous manufacturer specializing in high-end audiophile-grade products. The company’s excellent R&D team features industry professionals with extensive experience in “voicing” high-end headphones and electronics.
HIFIMAN’s EF400 is a DAC/Amplifier with a four-channel potentiometer that operates with ultra-high efficiency and low power consumption at maximum stability. Designed for a variety of applications, the EF400 is embedded with HIFIMAN’s Hymalaya R2R DAC, which was developed by the company’s engineering team. The Hymalaya DAC is composed of a resistor array that contributes to its outstanding sound quality, high-resolution output, and low power consumption.
The sound quality is maximized by incorporating high-quality components and precise processing technology.
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 360 resistor equivalent load. The result: fully balanced output that is beyond compare. br> The Soul of EF400 - Hymalaya DAC
HIFIMAN is famous for its audiophile headphones and digital audio players. As a company that is committed to satisfying the demands of discerning listeners through advanced, yet cost-effective designs, HIFIMAN is proud to present its latest achievement: the Hymalaya DAC.
The result of five years of focused product development, the Hymalaya DAC retains the acclaimed R2R architecture, but with a unique algorithm on an FPGA Chip that reduces electrical interference between the chip and peripheral components. Signal-to-noise ratio, total harmonic distortion (THD) and energy consumption are at their most efficient and cost-effective.
Hymalaya is a discrete R2R DAC (digital-to-analogue) module that is based on the FPGA algorithm. The combinations of its low audio frequency range, out-of-band noise, and low energy consumption make it a perfect match for high-performance audio equipment. The Hymalaya DAC module supports the standard PCM music signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum resolution of 24-Bit.
