Hey guys, HiBy is about to launch its third generation R6 Android DAP (expected to ship mid-February), and in anticipation you can leave comments and impressions here. I currently have a sample in-house for review, and will be sharing my thoughts in the coming days and weeks, so stay tuned.

Meanwhile, pre-orders for the new DAP are live here: https://store.hiby.com/products/hiby-r6-gen-iii

Liked the last one. I’m surprised at the price. It appears this one will be $500. I believe the last iteration was $800.

The first portable player in the series to use Class A amplifier circuit design. Dual ESS9038Q2M decoders, equipped with three independent power supply lines and an upgraded Android 12 system, achieve a higher balance than the previous generation in terms of performance, sound quality, and power consumption.

After various stages of updates such as RS2, R5II, and RS8, HiBy finally launched a brand new body in the mid-range market.

Compared with the previous generation, the internal structure, software, and most important tuning direction have been fully evolved! Starting from the amplifier circuit, R6III (third generation) added Class A/AB amplifier mode switching to the 6 series body for the first time. With the strengthened power supply network, users can get more stable output power and sound details; the processor And the system version has been upgraded, corresponding to the new Android apps in the future, and also paving the way for the new features that HiBy will bring.

feature of product
Dual ESS9038Q2M decoders - dedicated independent power supply lines
R6III uses a pair of ESS9038Q2M decoders as the main axis. The biggest difference from the previous generation is that the current output mode is changed to the voltage output mode to match the Class A amplifier circuit of R6III. Part of this generation of decoder is directly powered by an independent line, which greatly reduces the mutual interference between hardware and can also give full play to the full performance of this decoder. Compared with the desktop decoder solution, the actual performance is higher and the power consumption is higher. The power is relatively lower; and the saved power, HiBy is placed on the design of the amplifier circuit that has a greater impact on the sound.


Class A amplifier circuit design
The Class A amplifier structure has the characteristic of maintaining the peak output at all times. Its response speed is excellent and the driving force is very stable. It is the guarantee of sound quality on many desktop computers or high-end portable players. However, its operating efficiency is low, most of the power consumption will be turned into heat, and it is also more sensitive to the quality of power supply, so it is relatively rare in the mid-level player market. The amplifying circuit of R6III is composed of two OPA1652 operational amplifiers, 4 ELNA audio capacitors and 16 hand-matched transistors; the power supply configuration is luxurious and divided into two independent circuits, which are respectively supplied to the filter and amplifying circuit components to ensure the integrity of the entire circuit In each case, there is an adequate and stable power supply. Compared with the previous generation, its tuning pays more attention to the three-frequency texture interpretation and dynamic restoration, which is an obvious improvement that can be heard as soon as you put it on the ear.


Class A/AB mode switches automatically
Users can switch between Class A/AB working modes to prolong the use time:
Class A: Constant peak output power. The drive is good, the response is fast, and the sound performance is outstanding .
Class AB: Efficient amplification mode, rich in balance between sound performance and battery life .


Rich decoding and output options
The ESS9038Q2M decoding used by the R6III supports up to DSD512 and 32bit/768kHz files, and also supports the most popular MQA 16x layer expansion. After bypassing the Android SRC restriction with DTA technology, streaming services can also output the highest sound quality!

In terms of analog output, the R6III has independent line output and analog output sockets, providing 3.5mm single-ended and 4.4mm analog outputs respectively.

Function upgrade - Android 12 added
For the continuously updated Android apps, in addition to upgrading the CPU to Snapdragon 665, the R6III also wrote a dedicated Android 12 system starting from the underlying data. With the removal of unnecessary operating data and the upgraded process of Snapdragon 665, the power consumption and digital interference of the entire system are greatly reduced.

In terms of extended functions, the R6III has pre-installed the HiByCast function when it leaves the factory, allowing you to control it on the phone through mirroring at any time, and match the various input and output options of this body:

  • Bluetooth version 5.0, supports two-way Bluetooth connection and many coding standards, such as SBC, aptX-HD, LDAC and so on. Support DLNA connection and Airplay output connection .
  • Type-C can be used as a computer sound card, mobile phone external decoder or coaxial output .
MSEB and new HiByCast mirror control
R6III has HiByCast, a new function of HiBy player, which allows users to wirelessly control various functions of R6III on smartphones in a more intuitive way, including operating streaming apps, playing, and selecting songs, which is more convenient to use.

In addition, R6III also added the MSEB EQ function and plug-in function that are popular with many users. The former is based on a simple interface and description, making it easier for users to adjust the appropriate EQ settings; the latter provides more tuning settings for modifying the underlying data, greatly changing the sound performance of the R6III.

It’s less powerful than R6 2020, R6 gen.3 provide 405mw only from 4.4 output
Basically Looks an R5 gen.2 with newer android 12 and better UI with faster CPU

4.4 no class a?
Would be an error, I took specs images from an HK store, next week Hiby would release full specs on their website
