HIFIMAN DAC Development History

For over 20 years, HIFIMAN is famous for its audiophile headphones and digital audio players. (DAP) HIFIMAN players traditionally feature the R2R DAC archi-tecture, which is composed of an array of resistors. Like magic, it transforms a series of l’s and 0’s into spellbinding music.
The resolution of this architecture is superb, but the accuracy of the resistance matrix calibration creates difficulties that lead to high costs and excessive energy consumption. Thus, the market typically employs the less expensive Sigma-Delta DAC, which measures well but due to the many intermediate links, the overall listening experience is not on the same level as R2R.
As a company that is committed to satisfying the demands of discerning listen-ers through advanced, yet cost-effective designs, HIFIMAN is proud to present its latest achievement: the HYMALAYA DAC. The result of five years of focused product development, the HYMALAYA DAC retains the R2R architecture, but with a unique algorithm on an FPGA Chip that reduces electrical between the chip and peripheral components. Signal-to-noise ratio, total harmonic distortion and energy consumption are at their most efficient and cost-effective.
Whether paired with the HIFIMAN RE2000 Pro or other earphones, DAPs with the HYMALAYA DAC architecture makes it easy to enjoy hi-res audio via the USB-C output of an ordinary mobile phone, making it a high-fidelity source that can compete with nearly any standalone DAP.

The Soul of HM800 – HYMALAYA DAC

HIFIMAN Независими изследвания и разработки, R2R Architecture DAC
HYMALAYA 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-perfor-mance audio equipment. The HYMALAYA DAC module supports the standard PCM music signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum resolu-tion of 24Bit.HIFIMAN HM800 External Hard Drive - Figure 3

Ultra Low Energy Consumption
The HYMALAYA R2R DAC in the HM800 is famotis for its low power consumption. At the same time due to the characteristidt of its voltage output, it only needs a simple amplifying circuit to achieve its excellent sonic output. Low energy consumptiptv ensures that the thermal, or Johnson noise is extremely low.

Concept-based NOS (None Over-Sampling) Filter Design 
The oversarnpling titter is Widely usedm audio DACs to alleviate weak signal aliasing and to push the quantization noise to the ultrasonic frequency band so that it can be cut off by the analog filter. However, it sometimes pushes the weak signals to the ultrasonic frequency band, cutting them out altogether.
The HM800’s HYMALAYA DAC is designed to draw on the benefits while eliminating the negative effects. With the HYMALAYA DAC, the best possible performance is achieved while preserving the most minute details of every recording.

Pure Output
Maximum output is 40mW, making it easy to match the sonic output of more expensive R2R devices.


The HM800 is packaged with several well-constructed high-end cables so that customers can use the DAC/Amp with their favorite earphones.
