HiBy RS2 II Digital Audio Player

Gold units shipping at end of October Four years after the original RS2 carved out a niche as HiBy's stripped down, R2R answer to Android filled DAPs, the RS2 II brings the third generation DARWIN architecture down from the flagship RS8 II into the same pocketable, dual card slot format. HiBy rebuilt the analog stage, moved to a new X1600E processor, and grew the screen by nearly half, all while keeping the player's original mission intact: no streaming apps, no Bluetooth, just a dedicated path from your files to your ears. Type and Technology DARWIN III audio architecture, the same platform debuted on the flagship RS8 II High precision R2R resistor ladder DAC with a new FPGA digital engine (35,000+ logic elements, 40 DSP units) running HiBy's adjustable FIR filtering, harmonic control, NOS/oversampling switching, and DSD direct processing Redesigned analog stage: four OPA1612 devices for fully balanced voltage amplification feeding four OPA1622 devices for independent per channel current amplification New X1600E dual core processor for system navigation 3.55 inch, 480 x 800 display, a 45 percent larger screen at 122 percent higher resolution than the original RS2 PureAudio HiByOS in a dedicated green and gold theme, with no Android, Bluetooth, or streaming apps Dual microSD slots, up to 2TB each and both active at once for up to 4TB of local storage Doubles as a USB DAC, a digital transport over coaxial out, and a source for external amps over Line Out Compensation circuit and DAC technology covered under Chinese patent ZL202110679601.X Sound Character We haven't had the RS2 II in our listening room yet since it was only announced today, so treat this as what the architecture promises rather than a verdict. It shares its DARWIN III platform and much of its analog stage philosophy with the RS8 II, a lineage the R2R crowd already associates with a natural, analog leaning presentation rather than a clinical one. The quadrupled current amplification stage is aimed squarely at complex multi driver IEMs, with HiBy citing better transient response and control over demanding loads. We will update this section once we've spent real time with a unit. Build and Comfort Standard Edition: aluminum alloy unibody in dark green, with a rear panel pattern that shifts subtly under light. 156g Limited Edition: brass chassis in place of aluminum, chosen for EM shielding and vibration damping as much as heft. Brass ages with handling, so no two units will patina the same way over time. Capped at 500 units worldwide HiBy states the body has shrunk despite the larger screen, though exact dimensions haven't been published yet Best For Listeners who want a dedicated, distraction free player to pair with high end IEMs Owners of a larger flagship DAP who want a smaller, simpler second player for travel or daily carry Anyone who specifically does not want Android, Bluetooth, or streaming apps in the mix What's in the Box Player, USB-C cable, and standard documentation. HiBy hasn't published a full accessory list for the RS2 II yet, so we'll confirm the final bundle (and whether a case is included, as with past RS launches) once retail units are in hand.
