MQA (Master Quality Authenticated) rendering to 16x

HiBy R6 includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. MQA’ or ‘MQA Studio’ indicates that the product is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. ‘MQA Studio’ indicates it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.


Install the HiByMusic app on your Android or iOS smartphone and you can control the R6 from afar using WiFi or Bluetooth, for browsing, playing, skipping tracks, adjusting volume, etc.

MSEB Systemwide MSEB tuning

The MageSound Eight-Ball (MSEB) is HiBy's in-house researched sound tuning algorithm for adjusting desired audio qualities such as warmth, note thickness, vocal positioning, etc. directly instead of splitting the audio up into numbered frequencies. On the R6 it is available as a systemwide module for effecting all audio played on the device.*

*other than MQA, which MQA prohibits from modifying.

"The HiBy RS6 is a deeply engaging and well-thought-out initial foray into the world of portable R2R Android DAPs... The ground-up conceptualization of Darwin and what it means to the portable audio user is probably the most salient aspect of all its features with that blazingly fast OS workflow already a staple of previous HiBy product releases.

Twister 6

"When I started testing RS6, I didn’t appreciate at first the power of Darwin architecture until fw 1.20 update and addition of new IEM presets... I realized how effectively and naturally this DAP could be finetuned without a need of EQ or MSEB effects... Also, RS6 is one of the fastest DAPs I have tested to date."

"Hiby’s RS6 borrows a lot of technology from said D/A converters, choosing a higher engagement factor, flow and natural textures above anything else. If there’s a DAP that tries to elevate your mood and cover your body with goose bumps, then Hiby’s RS6 is definitely that one."

@gLer - Headphoneus Supremus

"A great DAP is the sum of all its parts – features, performance, stability, design, UX and sound quality. In my experience, few other DAPs comes close to the RS6’s combination of features, flexibility and sound quality, and no other DAP offers all of that plus R2R in one sweet and shiny copper package. Highly recommended."

"The HiBy RS6 is a wonderfully designed, elegant player that provides many features in a complete package. You have streaming, advanced DSP settings, DTA, Hi-Res Bluetooth, micro SD support, a very fast CPU with a clean UI, 4.4mm BAL and 3.5mm SE outputs in a very rigid copper chassis. This is a dream DAP when it comes to online music streaming. I appreciate HiBy’s first effort on their new, in-house “Darwin” R2R Architecture. I’m sure they can build upon this and reach greater heights. "
