Hiby RS2

R2R is for the purists, and few get purer than RS2. HiBy Music distilled the necessities from their pioneer RS6 for pure file music playback in a mini-form factor.

Clearly enough, to land on Headfonia, and Audiophile-Heaven‘s, Recommended Buys list, with no shortage of the R2R experience for Headfonics.

While being the smaller sibling, RS2 plays music back with a sonic truth and a particular delicacy and refinement only possible from R2R, but different to its Darwin V2 counterparts.

Those with a tremendous personal music library of files will be particular enamoured with RS2’s dual micro SD card slots for up to 4TB of storage.

ĐỌC THÊM: Darwin R2R sees HiBy set the bar

PCM and DSD will be decoded up and down RS2’s ladder of individual resistors, in the second generation of HiBy’s low-powered, battery-friendly, Darwin architecture.

With the work and skill it takes to design one’s own R2R resistor DAC from scratch, we must say: RS2, like RS6 before, is proof of how far up the ladder HiBy have climbed. [Xem thêm mô tả sản phẩm]

We’ve heard multiple times it’s not a matter of parts but the implementation that counts. So we pay attention when RS2 coverts PCM and DSD via separate circuit paths, doing so for the former ala typical R2R – NOS (non-oversampling). 

Đây thực sự là một thành tích gấp đôi bởi yêu cầu về độ chính xác tuyệt đối của các giá trị điện trở càng trở nên khắt khe hơn bao giờ hết — đây chính là chìa khóa tạo nên chất âm mượt mà như nhung, tự nhiên và khả năng bóc tách chi tiết cực cao vốn đã làm nên tên tuổi của DAC R2R.

Lovers of reference sound need not fret, however, with the ability to switch PCM decoding from NOS to oversampling mode for the cleanest possible result. That scrubs any last distortion and artifacts beyond the audible human hearing range.

HiBy make the distinction between PCM and DSD, because RS2 separately converts the latter with the most purity ever encountered in a portable device till date. Instead of pre-conversion to PCM as many other off-the-shelf DAC chips do, RS2 preserves the original DSD file throughout the process. 

Believe it: HiBy decode natively in DSD’s true 1-bit process. RS2 calls for a simple low-pass filter for the purest, most elegant portable DSD conversion that preserves the simplicity of the process and original waveform. Amidst minimal digital filtering, the format’s analog-like goodness gets delivered unmolested to your ears.

RS2’s dedicated and separate R2R PCM and DSD circuit paths mean you stand to enjoy the best sound you thought possible from either form – impossible to this extent, till now. 

The final product goes through JRC’s NJW1195A digitally-controlled analog volume control before reaching the output amp, for preservation of your music’s true resolution, and that very special, discrete, native DSD decode.

The sleekest, latest version of HiByOS allows you to navigate basically between your albums, artists, files and folders as you wrote them to your SD cards. With 4TB of external file storage, and up to 10 hours of playback, get back on the road with maximum portable fidelity in 2022.
