HiFiMAN EF400 + Ananda Stealth bundle

HiFiMAN EF400 Balanced Desktop DAC/Amplifier

Massive Power (4.4W!) and Superior Sound from a Sleek and Stylish Chassis. The HiFiMAN Himalaya DAC inside this HiFiMAN EF400 DAC/Amplifier received a VGP Gold Technology Award (Japan, 2022).

In 2012, Dr. Fang Bian and his team at HiFiMAN introduced the EF6, the legendary desktop DAC/amplifier that delivers gobs of power for a wide, detailed soundstage.

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 HiFiMAN 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.


EF400 features

  • Himalaya R2R DAC Module
  • Oxygen free copper wire wounded toroidal transformer
  • High current amplifier circuit
  • 30,000uf large capacitors
  • High/Low Gain Switch and choice of NOS/OS filter


Fully Balanced

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.


HiFiMAN Ananda Stealth

HiFiMAN Ananda Stealth is designed for music lovers who want one high-performance, extraordinarily comfortable headphone for all personal listening, whether it’s a home system, high-resolution portable player, or an everyday smartphone,” said Dr. Fang Bian, Founder and CEO, HIFIMAN. “The word ‘Ananda’ is derived from the Sanskrit term for ‘bliss,’ which is what this headphone will bring to anybody who enjoys audiophile-grade performance, no matter the source.”

HIFIMAN engineers employed lightweight, ultra-fine planar drivers for the high power sensitivity necessary when used with streaming audio devices. Ananda’s rating of 103dB guarantees that it will provide consistently low distortion high-fidelity output when used with a smartphone, let alone current and upcoming high-resolution digital audio players and home audio systems.

The industrial design of the Ananda headphone represents new standards of comfort and performance for open-back planar models. The ultra-thin diaphragm produces unmatched detail and low distortion, and the window shade grill design reduces sonic reflections, resulting in pure, neutral sonics.


Stealth Magnets

Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generating interference.

HIFIMAN’s advanced magnet design is acoustically transparent dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range.


Neo Supernano Diaphragm

The all new NsD is 80% thinner than previous designs resulting in a faster more detailed response while retaining lush musicality never before possible. At between 1 to 2 microns thick, the NsD diaphragm sets all be standards.

HIFIMAN has advanced its manufacturing processes to create this all new planar driver at unheard of prices. HIFIMAN has again set an all new bar for performance/value ratio that the rest of the industry will have a very hard time following.
