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

Specs:
Signal to Noise Ratio:112dB
Output Power: 40mW*2
THD+N (DAC Module): 0.0025%.

The HM800 will be available in March at a suggested retail price of $299. It will be available from authorized HIFIMAN dealers and the company’s online store, http://store.hifiman.com/.

I think this is a great idea. The dongle away from the phone/pocket and more midline has something I've wanted to see for a while. Hope the implementation works well. Nice work.

 

[kadinh]

thats actually pretty cool! i like it.

 

[Ceeluh7]

Wow, cool concept. I'd like to see more of this lil guy

 

[InvisibleInk]

I don't need it, but I'm going to get it anyway!

I have a feeling the MMCX cable won't connect to my ER4SR, though.

Will it connect directly to an iPhone or will it require an adapter?

It looks super compact. The price is reasonable too.

 

[syazwaned]

The pricing will make it a direct competitor to ru6

 

[mochill]

Very interesting stuff

 

[Steve Wilcox]

So, long digital and short analogue cable. I wonder what impact that will make?

 

[wric01]

Cayin ru6 seems better r2r with display, in and output. Proprietary cabling is negative but if it out performs ru6 then it's worth the extra 50$.

 

[Ynot1]

Doesn't the interface allow you to use any quality headphone cable when you want to use the R2R DAC as a preamp?

 

[wric01]

Dual headphone input vs common single headphone inputs of all other devices in market.

 

[jmwant]

Its a good thing that all the common connectors are included in the package.

 

[jaydoc1]

Looks an interesting take on dongle design - anyone tried it out / purchased it yet ? Would be keen to hear what Headfier's think about its sound performance before pulling the plug on ordering .....
