The new R2R King
The time has come: After the great RS6 and the new, great Mini-R2R DAP RS2, Hiby is going all out: The RS8 is probably the most uncompromising and consistent R2R DAP that has ever been developed and Hiby is preparing to become the king L&P P6 Pro from the throne!
Reviews
TheHeadphoneList
"The very first words that come to mind on first hearing the RS8 are expressive, expansive, nuanced and refinedThere's a vibrancy to the sound that engages you almost immediately, not as an overwhelming 'shock to the senses', but rather it just sounds genuinely large, life-like and dynamic"

The unboxing experience will be truly luxurious:
1Darwin II architecture
The Darwin architecture is a completely new high-resolution digital signal processing architecture developed by HiBy itselfIn a groundbreaking evolution of the traditional R2R architecture, the system includes advanced features such as linear FIR filters, non-linear harmonics control, switchable oversampling/NOS and DSD bypass on portable devices for the first timeThe flexible end-to-end architecture is fully configurable, providing endless possibilities for future upgrades and endless evolution
The Evolutionary Darwin Audio Architecture II
The R2R resistor ladder consists of 12 high-speed switches and 184 high-precision resistors, twice the number of the last generation
This means a doubling of the number compared to the last generation, effectively increasing dynamic performance and audio fidelity at low signal levelsA DC offset correction circuit allows the use of a fully DC coupled output stage, resulting in pulse responseSampling rates of up to 1024x DSD and 1536kHz PCM are supported, exceeding the specifications of many large systems in one portable device!
Darwin I: 6 high-speed electronic switches, 92 high-precision resistors, unipolar
Darwin II: 12 high-speed electronic switches, 184 high-precision resistors, bipolar15dB dynamic improvement compared to 1st generation Darwin architectureGeneration
R2R technology
The heart of the R2R resistor ladder DAC architecture is the high-precision resistor ladder, which consists of 12 high-speed switches and 184 high-precision resistorsThe digital signal, through the
high-speed electronic switches, controls the control voltage, which is modulated by the resistor network to obtain an analog voltage waveform that corresponds directly to the digital signal, making the high-frequency modulation of D-S DACs a
natural, transparent and emotional display enabled
Linearity Compensation with Resistor Ladders
Effectively reduces non-linearity caused by resistor mismatch in the R2R networkTogether with the Darwin architecture's unique harmonic control system, a more relaxed, natural listening experience is possible
NOS/OS mode switch
NOS mode is a non-oversampling mode that responds to signals more immediately and directly, converting the digital signals directly into analog signals
Converts signals directly into analog output signals, resulting in a more analog sound signatureIt is more suitable for music files/streams with a sample rate of 192kHz or higherThe oversampling mode eliminates aliasing artefacts through the proven combination of oversampling and ultrasonic low-pass filter, resulting in superior measurement performance and enables all functions of the Darwin architecture as well as an individual adaptation of the sound signature to different headphones
Audio's own femtosecond crystal oscillators
2x femtosecond precision quartz oscillators, clocked at 45.158MHz or49.152MHz dedicated44.1x (including DSD) and 48x (including MQA) kHz family of audio format sampling rates, with phase noise of only 159dBc/Hz @1KHz offset ensure accurate reproduction of all music formats with no audible
jitter effect
2Audiophile component selection
A new high in component costs
Hand-picked gold-tantalum capacitors ensure a clean output power, a higher residual ripple of the power supply and a lower distortion factor of the resulting systemEquipped with 4 Elna SILMIC II silk fiber capacitors for silky high tones
comparable to tube amplifiers! Complete with 47 high capacitance tantalum capacitors, 10 Panasonic thin film POSCAPs, get your money's worth only in audiophile quality capacitors inside the player!
Class A headphone amplification
The class A amplifier consists of 2x OPA1652+8x NXP double bipolar transistors and features zero distortion and instantaneous transient response;
The class A amplifier maintains its peak performance at all times and has ideal drive and control characteristicsThe amp is capable of driving full-size headphones, high and low impedance IEMs, and all kinds of difficult loads with ease
The RS8 maintains a composure befitting a modern flagship while steering every complex passage of music through every headphone load
Turbo mode
Everything included! Full power output! Turn on turbo mode to get 25% more power at the touch of a button! Everything included for maximum musical performance!
Headphone amplifier power supply: standard ±6V, turbo at ±7.5VWith Power = V^2/R, Turbo mode gives 56.25% additional power
(The heat output and battery consumption increase significantly when the turbo mode is switched on)
12000mAh power bank
A huge battery specially designed for the occasion ensures sufficient power supply and battery life for the Class A amplifier, which is suitable for both immediate musical transients and for the long-haul is suitable: 12 hours on 3.5mm SE and 8 hours on 4.4mm balanced for longer listening!
Playtime PO 3.5mm: Class-A 8h, Class-AB 12h
Independent power supplies
Digital, DAC, preamp and postamp circuits are each powered independently to avoid interference
The headphone amplifier circuit is powered by 2 high quality DC/DC transformers and 6 high magnetic, ultra low internal resistance and fully shielded high power coilsThe 3.5mm SE and 4.4mm balanced
headphone outputs are completely separate
The ultrasonic low-pass filter is fed by another DC/DC transformer and 7 LDO regulators, which drive the left and right channels independentlyThe R2R ladder is powered by another DC/DC transformer and 2 ultra-low ripple LDOs, feeding each channel independently
Strong and cool
The battery housing made of pure copper ensures high heat dissipation and thus cool internal temperatures, even in the toughest operating scenarios
