In 2012, Dr. Fang Bian and his team at HiFiMAN introduced the EF6, the legendary desktop DAC and amplifier that delivered gobs of power for a wide, detailed soundstage.
Years later, HiFiMAN is proud to introduce a new model, the EF400 that incorporates the very best of recently developed technologies, highlighting their advanced HIMALAYA R2R DAC. The EF400 is the modern desktop DAC and Amp solution with a compact footprint and affordable price, but with sonics that outperform products many times its size.
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 and amp.
The differential amplifier circuit features a maximum output of 10.7 Vrms (THD <1%) on a 36Ω resistor equivalent load. The result: fully balanced output beyond compare.

Great sounding R2R Dac, powerful Amp. Punches way above it’s price point !!
Pairing this amp with my Meze Elites is just incredible. Prior, I have heard the Elites on a Cambridge Dacmagic 200m and a FiiO k5pro ess. The sound from this amp is just heavenly paired to the other amps listed. I understand now what they mean regarding soundstage, tonality, depth and so on. So easy to get lost in the music. This really has everything sounding amazing and as I understand it both the cans and the amp will just get better with time.
Pros: Amazing R2R sound and price coming from ESS dacs & amps. Everything you need and nothing you don’t if you are simply hooking up to a comp or iPad via USBC. Great packaging for what it is in my opinion, everything appears to be high quality.
Cons: I have seen Hifiman around the forums about QC issues on lower end cans so reliability is a concern, especially with flagship headphones attached.
If this thing lasts forever, I wouldn’t feel an urge to upgrade as I don’t know how much better this can get! Great experience with Bloom as well, answered my email about a price match way outside of business hours and instantly had a link in my email. Will keep purchasing here for sure!
Highly recommended. Great build quality.
