HiFiMAN EF400 Amp Headphone Amplifier
The HiFiMAN EF400 is an advanced headphone amplifier and digital-to-analog converter (DAC) that offers exceptional sound quality in a compact, elegant package. Featuring Hymalaya R2R DAC technology and a four-channel differential design, the EF400 delivers sound with unparalleled detail and depth. This device is ideal for audiophiles and professionals alike who are looking for an exceptional listening experience.
Hymalaya R2R DAC - the heart of the device
The EF400 features the Hymalaya R2R DAC, based on high-precision resistors and an optimized FPGA algorithm. As a result, the technology reduces electrical interference and provides an excellent signal-to-noise ratio and low harmonic distortion (THD). The Hymalaya DAC guarantees faithful sound reproduction, offering natural sound with clearly rendered details.
Four-channel design
The amplifier's unique four-channel differential design enables exceptional balance of the audio signal. As a result, the EF400 delivers a maximum output power of 4.4 watts per channel into a 32 ohm load, allowing it to handle both low-impedance headphones and more demanding models. Full signal balance translates into a wide soundstage and excellent dynamics.
Versatility and richness of connections
On the front panel of the EF400 you'll find a variety of headphone outputs, including 4-Pin XLR, 4.4mm balanced, and 6.35mm and 3.5mm single-ended. On the rear panel, meanwhile, you'll find RCA (single-ended), XLR and two USB ports (Type-C and USB-B) for easy connection to computers, smartphones or other audio sources. Such versatility makes the EF400 ideal for a variety of configurations.
Intuitive operation and modes
The EF400 features a four-level mode switch that allows users to choose between OS (Oversampling) and NOS (Non-Oversampling) settings in high and low gain modes. This allows users to adjust the sound characteristics to their preferences and the type of headphones connected, allowing the device to realize its full potential.
Robust construction and stylish design
Made of high-quality materials, the EF400's housing features a sleek, minimalist design that perfectly fits in with the aesthetics of modern audio systems. Compact dimensions (246.5 x 228 x 61 mm) and a weight of 3.08 kg make the unit easy to set up and stable during use.
Performance and reliability
The EF400 is designed with stability and performance in mind. Efficient cooling and high quality components ensure reliable operation even under heavy use. This is an amplifier that will meet the expectations of the most demanding users, offering long-lasting reliability and an exceptional listening experience.
