Hiby RS2

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). 

That's double the feat because the precision demanded in exact resistor values – for the buttery, natural and resolving ability that R2R DAC topology is known for – goes up.

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.
