HIFIMAN EF400 Balanced Headphone Amplifier/DAC Preview

See the complete review for the HIFIMAN EF400 DAC/Headphone Amplifier.

HIFIMAN has released its first new desktop amplifier/DAC in ten years, the EF400.

The EF400 uses HIFIMAN’s new Himalaya R2R DAC, which uses an array of highly accurate resistors for a “ladder” method of conversion. This DAC supports the common PCM signal with a maximum 24-bit resolution. Its headphone amp offers the fidelity of Class A design and the efficiency of Class B architecture, and can produce up to 4.4W per channel.

The front panel gives you FOUR balanced headphone outputs, so you use it to listen to a wide variety of headphones. On the back are input jacks for USB-B, USB-C, and RCA sources, and dual XLR three-pin balanced outputs.

That is a lot of versatility, but how does it sound? The HIFIMAN EF400’s suggested retail price is $599US. I’ll listen to it with several pairs of headphones and report back soon.

Gene Hopstetter

Gene Hopstetter has been collecting records since 1981, when he walked into a record store and spent all of his allowance money on every AC/DC album he could find. In the mid-1980s he worked as a stock-boy in a neighborhood hi-fi emporium, which is when his obsession with sound quality began. He has always had a record player and vinyl in his life. Gene was born and raised in New Orleans, where music and food were invented. In the 1980s and 1990s he was active with two university radio stations, KLSU in Baton Rouge, and WTUL in New Orleans, where he got involved with local music promotion and album production. He earned degrees in Creative Writing and Journalism from LSU, which he somehow manages to use in his current career as an IT professional. When he is not listening to music, reviewing components, or updating his collection on Discogs, Gene enjoys restoring vintage Garrard turntables and cleaning LPs with his ultrasonic cleaner. His most prized vintage hi-fi components are a pair of McIntosh MC30 tube amps, a Garrard 301 cream grease bearing turntable with two tonearms, and a Thorens TD124 turntable. Gene is also interested in contemporary developments in hi-fi, such as Raspberry Pi DACs and streamers, amplifiers with Gallium Nitride transistors, and phono preamplifiers with digital output.
