Since there were some rumorses about the upcoming HiBY R6 Pro DAP and since the company has already released full description officially and smaples should soon become available - starting this thead to shed some light and have a discussion. I would try to keep this thread well stuctured, gathering FAQ and usefull links in first post. I would also update with the release dates.

Main differences with HiBY R6:
Audio:
Additional LPF components:
MUSES8920 as I/V:
Adhering to the motto ‘ Make Music More Musical’, R6 Pro leverages four low-pass filter chips MUSES8920, two low-phase-noise, high-precision active crystal oscillators, which delivers a superior high-definition sound. Empowered by Panasonic Polymer Capacitor with Low-ESR and Elna SILMIC audio grade capacitors, R6 Pro runs the dual ES9028Q2M into current output mode resulting in a strong anti-interference ability. The comprehensive upgrade of R6 Pro wiring scheme will bring you the unmatched and high-quality sound, allows you to immerse yourself in lossless music.
4.4mm balanced audio output instead of 2.5mm:
Japanese NIPPON DICS 4.4 Balance Base:
With larger physical space, the 4.4 balanced base equipped in HiBy R6 Pro boosts the level of reliability and immunity. The 4.4 balanced base created by Japan NIPPON DICS delivers flawless performance in connection to revolutionize a plug and jack set for headphone.
More output power on both outputs:
3.5mm unbalanced: 245mW V|S 120mW in R6
4.4mm balanced: 750mW V|S 300mW in R6
Wonder why only 8-150Ω are specified - seems that this DAP is capable of driving 300Ω and more to an appropriate level now.
General:
Android OS is now 8.1
Screen is covered with Gorilla Glass
No changes to general HW part (CPU, RAM, ROM, connectivity)
