## Features

- Massive power and superior sound from a sleek and stylish chassis: The 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. Ultra-high efficiency and low power consumption at maximum stability:4.4W per channel balance output. Embedded with HIFIMAN HIMALAYA R2R DAC- Recipient of 2022 VGP Gold Technology Award (Japan).
- Experience the prized performance of the R2R DAC: HIMALAYA is a discrete R2R DAC (digital-to-analog) 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
- Full Balance: 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.
- 4-level Function Switch: High Gain NOS, High Gain OS, Low Gain OS, Low Gain NOS ★Headphone Out (Front Panel): 6.35mm Single-ended; 3.5mm Single-ended; 4.4mm Balanced; XLR 4-Pin Balanced Output. ★Line Out (Rear Panel): CANNON Balanced Output; RCA (Single-ended).★ Input: USB Type C; USB-B

## Questions & Answers

**Q: Nos = no over sampling and os = over sampling?  if so, how much over sampling?**
A: The EF400 uses HiFimans 'himalaya' R2R DAC which is a custom resistive-ladder chip using individual precision resistors to perform the D->A conversions. Because Dr Bian's decoding arrays are inherently very accurate, they don't benefit much from oversampling unless the digital source is very poor and by not oversampling, its analog output has no sonic artifacts left over from an oversampling stage that must be filtered away.

So I think that the himalaya's oversampling mode is very low like 2 or 4X - HiFiman doesn't disclose their sampling rates, but it doesn't matter - unlike delta-sigma DACs, that must oversample to minimize the distortions inherent in their D->A conversion and the digital filtering required to reduce them to acceptable levels - R2R DACs oversample to increase their conversion accuracy and dynamic range and require little or no post-processing of their analog output.

I've had this EF400 for about a year, and its been flawless, it drives power-hungry planars like HiFiman Edition XS, or Monoprice M1070 with control, authority, and revealing detail. Conversely, switch to its low-output range, and sensitive dynamic headphones like the HiFiman HE-R9, or Harmonicdyne Poseidons are presented against an utterly 'black,' noiseless background.

Yeah, 500 dollars is a pretty stiff hit "Just to listen to headphones..." but I believe that the EF400 is pretty much the end game for any setup costing less than six figures.

Cheers
Jim

**Q: can it be used as preamp fot active speakers and control the volume from both?**
A: No. The rca jacks are fixed volume and the volume knob on the front only controls the headphone jacks.

**Q: does this dac/amp works with Playstation 5?**
A: As long as your PS5 has a USB out, which I think it does, the amp should work. The EF-400 only takes USB-B or USB-C, no optical or USB-A. So be aware of that.

**Q: Will this power the Hedd Heddphone or any other hard to power Headphone with enough power?**
A: I think it has enough power for planar. However, it may not listened good for some headphones, such as LCD-X. You can try it
