R5 (Gen2) Audio Componentry

A-class class-A amplification

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.

Discrete output stage

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 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

Utilizing dual independent audiophile-grade crystal oscillators at 45.158MHz and 49.152MHz provides high precision timing for all audio events in your music.

Cost-no-object audio componentry naturally lays the path to quality sound

Employing 163 high-precision resistors, 19 Panasonic tantalum POSCAPs, and 4 ELNA electrolytic capacitors maximally suppresses power supply ripple, yielding silky black backgrounds.

Succeeding the first generation of good sound and outstanding performance/price ratio and MORE UPGRADES!  The R5 gen 2 is the only Android DAP of its price class boasting class A headphone amplifier circuits, making for an outstanding audio performance.

"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.

"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."

"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. "

"The HiBy R5 Gen is a very welcome addition to what has become a somewhat sparse-looking $500 and below DAP market in 2022. You need an edge these days, something unique or easily defined to make your digital player stand above the swarm of dongles nipping at your toes. The Class A mode of the R5 Gen does exactly that and to be frank it’s the only mode you need with the lesser Economy mode really more of a backup to get to that very impressive 30-hour battery life."

"I feel like HiBy can start to use this Class-A amp design with its other models even the higher end ones. For just 449$ it does a very good job in terms of dynamism, clarity, timing and attack. When I started to listen to it for the first time with the amp closed, I told myself; ”so it’s just another R5”, but that turned out not to be the case when I switched on the amp." The HiBy R5 Gen is included in Headfonia's Best DAP Recommendations list!

R5 Gen 2 is quite an attractive proposition not only because of its neutral sound signature, all the 3 popular types of outputs on offer (3.5mm SE, 2.5mm BAL and 4.4mm BAL), swift user interface, excellent ergonomics and easy to love, well executed HiBy OS but also because it offers 2 separate Amp modes that actually sound different and an excellent 35 hour battery life in Economy mode, which is almost unheard of with Android DAPs.

"Class A amplification in this price range is also unheard of, and ups the ante in balanced mode, making this a fantastic source with more demanding, higher-end headphones, too. I do wish a volume knob would have been included instead, which just adds to the list of improvements that are on HiBy's more expensive players. The market for such dedicated audio players is in my opinion going to increase, and HiBy with the new R5 Gen 2 is well placed to makes its name here."

"As a standalone music player, however, the R52 comes into its own, with all-day battery life when you’re out and about on hikes or at the gym, and a step-up in Class A sound quality when you’re listening intently at home. Coupled with HiBy’s rock-solid software platform, the R52 is the ideal pocketable music player for almost any occasion or use case, and despite some obvious shortcomings, it still ticks almost every box: usability, versatility, reliability, sound quality, and wired/wireless compatibility."
