Its a modern DAC/amp solution with a compact footprint and price to match, but with sonics that outperform products many times its size.The HIFIMAN EF400 is a DAC/headphone amplifier that provides great sound quality and will power a wide variety of headphones, reports Gene Hopstetter in his review for Secrets of Home Theater and High Fidelity. Its selling price delivers quite a bit of versatility, and it should be easy to implement within a wide variety of devices with USB output.The HIFIMAN EF4000 is an elegant piece of gear that is simple to use but has a sophisticated sound signature that’s slightly bright tilted, rather neutral, and natural but it punches hard when it has to, notes Louis, headphonics.com, October 19, 2022. Construction is hefty, to say the least, and you will realize that the first time you hold one physically. The front panel has a balanced-looking design that will look good anywhere you place it...Discrete HIMALAYA DACIn 2012, Dr. Fang Bian and his team at HIFIMAN introduced the EF6, the legendary desktop DAC/amplifier that delivers gobs of power and a wide, detailed soundstage. Ten years later, HIFIMAN is proud to introduce the new model EF400, which incorporates the best of recently developed technologies, especially the company’s advanced HIMALAYA R2R DAC.The HIMALAYA is a discrete R2R DAC 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 HIMALAYA 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 24Bit.Fully Balanced DesignThe four-channel differential structure features a DAC, buffer, and active filter that add up to unbeatable fully-balanced output for a Class AB DAC/amplifier. The four-channel fully differential amplifier circuit features a maximum output of 10.7 Vrms on a 36? resistor equivalent load. The result is fully balanced output beyond compare.Oodles of ConnectivityAllowing you to take maximum advantage of the EF400s capabilities is a wealth of connectivity choices. It boasts four front panel headphone outputs consisting of a 6.35mm single-ended, 3.5mm single-ended, 4.4mm balanced, and XLR 4-pin balanced output. The rear panel includes an XLR balanced stereo output pair and an RCA single-ended stereo output pair. Also onboard are USB Type C and USB Type B connections.A four-level front panel control lets you select High Gain NOS (No Oversampling), High Gain OS (Oversampling), Low Gain NOS NOS (No Oversampling), or Low Gain OS NOS (Oversampling) to tailor the output perfectly for your headphones. There is also a high-quality volume control.OverviewSleek, stylish, powerful headphone amp / DACHIMALAYA R2R DAC module4.4WPC outputOxygen-free copper wire wound toroidal transformerLarge 30000uf capacitorsFour headphone outputsTwo USB inputsFour-level gain selector with oversampling / no-oversampling optionsHigh-quality volume controlOutputs6.35mm single-ended headphone out3.5mm single-ended headphone out4.4mm balanced headphone outXLR 4-pin balanced headphone outRCA line outXLR balanced line outInputsUSB Type CUSB Type BSpecs:Signal to Noise Ratio: 118+/-3dB (A Weighted)THD+N (Line out): Between 0.002% and 0.004%Channel Separation: 125+/-3dBMaximum Power Output: 4.4 W per channelDimensions: 8.9” wide. 9.7” deep. 2.4” highWeight: 6.7 lb.
