Listeners just can't resist resistor-ladder DACs, and the same can entirely be said for HiBy Music's discrete R2R RS6.

Your music will be decoded up and down RS6's ladder of individual resistors. And with the work and skill it takes to design one's own R2R resistor DAC from scratch, we must say: RS6 is proof of how far up the ladder HiBy have climbed.

We've heard multiple times it's not a matter of parts but the implementation that counts. So we pay attention when RS6 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 RS6 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, RS6 preserves the original DSD file throughout the process. 

Believe it: HiBy decode natively in DSD's true 1-bit process. RS6 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.

RS6'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 an analog volume control before reaching the output amp, for preservation of your music's true resolution, and that very special, discrete, native DSD decode. No detail is too small for HiBy, and it stretches to software.

With Head-Fi's best Google Play Store and Android 9 UI at your fingertips, audiophiles will enjoy the natural, fatigue-free detail of RS6. Use any streamed music service ranging from 16X Tidal MQA, Spotify, full Hi-Res Lossless Apple Music and Roon, to YouTube, Plexamp and Soundcloud.

Hear this in tandem with C9 – owners of Cayin Audio's flagship portable tube amp should also seek out RS6 for a tremendously thorough R2R source complete with hardware line-out port.
