Introducing the HIFIMAN Fully Balanced HM800 Mini-DAC/Amplifier

The new HM800 earphone DAC/amplifier relies on R2R architecture, a chip composed of an array of resistors, but with a new algorithm that reduces power handling between the chip and peripheral components. Signal-to-noise ratio, total harmonic distortion, and energy consumption are at their most efficient and cost-effective..

Its miniature proportions – approximately the size of a U.S. quarter -- make the HM800 a perfect match for high-performance audio equipment. In addition, we emphasize maximum flexibility, with a USB-C input and four cables included for connection with the majority of high-end earphones on the market: USB-C, MMCX coaxial, MMCX-0.78 and MMCX-0.75 pin connector cables.

Designed to turn any smartphone into a high-resolution audio source, the HM800, which, from its DAC to its amplifier is fully balanced, combines a low audio frequency range, out-of-band noise, and low energy consumption to create a high-performance match for in-ear monitors at any price point. The internal HIMALAYA DAC module supports the common PCM signal transmitted by the most common IIS (Integrated Interface of Sound) audio interface, with a maximum 24Bit resolution.

The new concept-based NOS (None Over-sampling) filter stands out from previous designs by minimizing noise without pushing weak signals to the ultrasonic frequency band, rendering them inaudible. With the NOS filter, the best possible performance is achieved, preserving the most minute details of a well-mastered recording
