HiFiMAN EF400 + Arya 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 Arya Stealth

The HiFiMAN Arya Stealth has become a household name in the audiophile community and for good reason. The latest Arya is the culmination of HiFiMAN’s commitment to performance and re-engineering. Never before has a company brought this kind of Planar performance at this price point. Fast, wide soundstage and mind-blowing detail make the Arya a must-listen. HifiMan Arya features a driver based on the HE1000 V2 headphones, one of the best drivers on the market in our opinion, which raises the sonic characteristics to a considerably higher level than similarly priced products.

“Our HE1000 series is an audiophile favorite. In particular, the 1000 V2 continues to be one of our best-selling models to date,” comments Dr. Fang Bian, Founder and CEO, HiFiMAN Electronics. “Our experience working and reworking the technology until we reached sonic perfection gave us the ability to adapt many of the same technical features in a headphone that is accessible to a wider audience of music lovers.”

With an ergonomic design to comfortably fit most listeners, the Arya incorporates unique HiFiMAN features such as the patented “window shade” system that reduces reflections to widen the soundstage. A super-thin diaphragm guarantees faster response and bare minimum distortion. As with all new HiFiMAN products, the Arya features 3.5mm headphone connectors that are angled at 10°, thereby lessening the pressure points associated with straight-angled connectors. These pressure points sometimes stress the connection, but the new design ensures a solid, reliable and long-lasting link between the headphone and the cable.


Stealth Magnets

Traditional magnets generate sound waves that can introduce interference. The special shape of HiFiman’s Stealth Magnets enables the waves to pass through without interference. This design is acoustically transparent minimizing the degradation of the sound waves and lowering distortion to produce accurate sonic output.


Nanometer Thickness Diapraghm

A breakthrough core technology developed by HiFiMAN, it’s the first of its kind in headphone applications. Working with this advanced material is extremely challenging, but the successful incorporation of this film as the Arya’s planar driver is the cornerstone of its remarkable sound.


Metal and High-Grade Plastic Construction

HiFiMAN designed the Arya’s high-quality metal headband with extra strength in view and a special high-grade plastic for lightweight comfort and rugged durability.
