HiBy R6 III

R6III brings its ES9038Q2M workhorses, and accompanying selection of seven digital reconstruction filters for sonic tweaking, to a new level of affordability. It entered Audiophile-Heaven's Hall of Fame. The Headphone List reiterated how complete a music player HiBy have introduced for the entry level.

The converted analog, decoded with the backing of a FPGA leashed to R6III's DACs generating I2S, flows as an accurate waveform on to a series of 16 discrete bipolar power transistors working in Class AB or an optimally pure Class A.

Doubling on its counterpart R5II's output device count, and differentiating itself from so many others who use op-amp ICs with inordinate amounts of gain, R6III's open-loop linearity remains excellent before application of feedback.

That's owed to its Class A bias ensuring individual output transistors are working in optimum condition – aided by an operating voltage of five volts.

Distortion and noise are kept low, without resorting to the excessive use of negative feedback. HiBy designed a true-balanced differential amplifier to further improve R6III's linearity, and you can count on common-mode rejection at its best whenever you plug in via 4.4mm.

R6III's current handling is impressive given its number of output transistors in parallel, meaning this HiBy remains unfazed driving even the punishing low impedances of Raven, Odin and Legend Evo from Empire Ears, the Vision Ears EXT and the Oriolus Szalayi.

And even this baby HiBy is able to supply its clean small-signal to the likes of outboard amps such as Cayin Audio's C9, via a dedicated 4.4mm line-out port.

By putting such a high-performance circuit in the palms of people's hands and offering them a Snapdragon 665 with full Google Play support, HiBy grant you the ability to bypass Android 12's sample-rate conversion for bit-perfect playback. Music is truly accessible to anyone and everyone. 

Discussing the above, it's so easy to forget we're talking about R6III as HiBy's entry-level offering. See what these forward-thinkers can really do higher up the range here, or view our other music players here.
