Faye Zhou

HiBy's launch event on April 15, 2022 unveiled the brand-new HiBy R5 gen 2 hires digital audio player and the Lasya earphones. The event featured some highlights such as the concept of  “a Class-A act debuts” and much more as we will find out below.

The Music Player: HiBy R5 Gen 2

 Class A headphone amplifier

Employing flagship grade class-A amplification in this mid-tier android DAP, the R5 utilizes Class A discrete balanced amplification circuitry, capable of continuous high power output, with plentiful energy reserves for all music genres. Converting power with ease for the most dynamic compositions, the sound is clear and full.

With 4 independent channels of push-pull amplification with 270° conduction angles constructed of discrete componentry, including 8 high powered paired bipolar transistors, the R5 provides excellent current output power and control over variable loads. Enable Class A headamp mode for class-beating audio performance! THD is down at 0.0006% at the amplified output for unparalleled realism.

Dual High-Performance DACs for astonishing music resolution

Dual High-Performance DACs for astonishing music resolution

Dual ES9219C DACs natively support DSD256, PCM768kHz/32bit high-res formats, with SNR of 130dB and THD+N down below -112dB.  Presenting a highly accurate output voltage, ensures the most accurate signal is given to the class-A amp section for amplification; also supporting integrated DAC-amp output (economy mode) for excellent low power consumption and extra long play time.

Dual independent crystal oscillators, FPGA clock algorithm
