Hiby FC6

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.

Proprietary digital filters aboard FC6's FPGA reconstruct audio and manage I2S flow to the Darwin DAC. That scrubs any last distortion and artifacts beyond the audible human hearing range.

HiBy make the distinction between PCM and DSD, because FC6 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, FC6 preserves the original DSD file throughout the process.

Believe it: HiBy decode natively in DSD's true 1-bit process. FC6 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.

FC6'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 decoded product goes through JRC's NJW72315 digitally-controlled analog volume control before reaching the output amp, for that very special 1-bit DSD decode, and preservation of your music's true dynamic range resolution.

Working hand-in-hand with its Darwin DAC, FC6 brings plenty of even-order harmonics to sweeten synergies given its single-ended operation throughout.

Eschewing bridge-tied load operation means FC6 also performs excellently into the low impedances typical of portable earphones and headphones, with one workhorse Texas Instruments OPA1622 power op-amp per channel.

Waste no time therefore turning your Android or iOS device into a Darwin R2R DAC in itself, with FC6. Also check out all of HiBy's releases here, or view our other music players here.
