Headfonia have already elected it to their Recommended Buys list, something that Audiophile-Heaven second. R6 Pro II is The Headphone List&#8216;s &#8220;instant recommendation at or below the kilobuck mark &#8230;\u00a0packs more technology than I\u2019ve seen in flagships only a year or two ago, with sound quality that comes oh so close&#8221;. R6 Pro II\u2019s AKM decode gets passed along beautifully to drive your prized headphones and earphones says\u00a0MOONSTAR Reviews. Audio Discourse writes HiBy hit it out of the park \u2013\u00a0empowered by a beautiful I\/V stage, Class A discrete transistor output stage, Android 12, full Google Play Store and streaming usability, plus\u00a0HiBy&#8217;s relentless drive to surpass previous limits.\u00a0[See Product Desc. For More] A modern-day music player is so much more than its DAC chips, and HiBy have taken that to heart \u2026 hoping everyone does too, to truly see the extent of their efforts. Greatness achieved at the highest end is easy, but portable digital audio has a new master in HiBy because of how much of that essence trickles down affordably into R6 Pro II. HiBy\u2019s effort means R6 Pro II is greater than the sum of its parts regardless of its entry price, and ensures the very best platform for Asahi Kasei Microdevices (AKM)\u2019s resurgent flagship DACs to make their mark.\u00a0 That\u2019s evident because of the mastery HiBy designed around AKM&#8217;s digital ecosystem. These Japanese giants,\u00a0back on their feet\u00a0with a clean slate, started afresh expanding the basic footprint of a single DAC chip IC into three separate parts \u2013 to similarly multiply capabilities by a factor of three. AKM\u2019s AK4191EQ DSP is the brains of the operation, receiving pristine I2S clocking and data from HiBy\u2019s FPGA. Aboard, AK4191EQ\u2019s delta-sigma modulator takes advantage of its expanded, dedicated, silicone footprint to lay claim to the title of the first chip IC working at seven bits. These seven single-bit modulators flow on into R6 Pro II&#8217;s AKM 4499EXEQ DACs, one for each channel and built with a single purpose in mind: to turn the interpolated, noise-shaped, digital data it receives into the most precise analog waveform possible afforded by its large footprint.\u00a0 Silicone size matters when it comes to a great DAC IC, and AK4499EXEQ has it.\u00a0Enabled by much more exact, matched resistors and capacitors aboard for precise DC single-bit decoding, and dynamic element matching that is less burdened by switching errors \u2013 granted by parts accuracy from a\u00a0bigger footprint. Any conversion errors from AK4499EXEQs outputting in current manifests as DC offset, and not total harmonic distortion, that is easily filtered out. That&#8217;s expected of any source claiming to be high performance.\u00a0 HiBy&#8217;s\u00a0eight-channel current-to-voltage I\/V section follows these AK4499EXEQs, befitting of chips that output in current for best distortion performance and indeed more expensive players.\u00a0 By treating each of the eight channel current outputs separately before stereo summing, R6 Pro II yields a small-signal stage that is transparent and, most importantly, accurate.\u00a0HiBy&#8217;s gain signal flows as a linear waveform on to a series of 16 discrete bipolar power transistors working in Class AB or an optimally pure Class A. Differentiating itself from so many others who use op-amp ICs with inordinate amounts of gain, R6 Pro II&#8217;s open-loop linearity remains excellent before application of feedback. That&#8217;s owed to its Class A bias ensuring individual output transistors are working in optimum condition \u2013 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 R6 Pro II&#8217;s linearity, and you can count on common-mode rejection at its best whenever you plug in via 4.4mm.\u00a0 R6 Pro II&#8217;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 Odin and Legend Evo from Empire Ears, plus the Vision Ears EXT,\u00a0Subtonic Audio&#8216;s\u00a0Storm, Focals, Fostexs\u00a0and Rosson Audio Designs. A separately regulated inductor-based power supply ably backs up this potent voltage source. And even this\u00a0overachieving HiBy is able to supply its clean small-signal to the likes of outboard amps such as Cayin Audio&#8216;s C9II, via a dedicated 4.4mm line-out port. By putting such a high-performance circuit and a big 5,000mAh battery in the palms of people&#8217;s hands and offering them a Snapdragon 665 with full Google Play support, HiBy grant you the ability to bypass Android 12&#8217;s sample-rate conversion for bit-perfect playback. This is what it means to truly step-up in 2024, and HiBy use the statement that is R6 Pro II to tell you how much more you should expect.
