With Delta-Sigma DAC chipsets becoming so ubiquitous in our globalized markets, R2R-based DACs are coming back in a big way. Once considered an outdated technology, many audio manufacturers are selling them as a contrast (in sound) to chip-based (ESS, Burr-Brown, AKM) devices.
To that end, HiBy has a new R2R Dac-equipped digital audio player called the HiBy RS2.
As per HiFiGo:
With HiBy’s in-house developed Darwin audio architecture, RS2 brings the goodness of R2R DACs with modern functions like adjustable FIR filter, Harmonic controller, NOS/OS Switch, etc. It is a pure audio player with the HiBy OS PureAudio version. There is no Android, just pure musical pleasure awaits you with the latest RS2. HiBy has designed the RS2 with a compact form factor, packing a complete R2R array in a retro design.
Other feature highlights include a high-current mode amplification circuit and dual headphone outputs, including a single-ended 3.5mm output and a balanced 4.4mm headphone output. You also get support for high-resolution PCM (up to 32-Bit/384kHz), DSD, and 8x MQA unfolding, plus it can operate as a USB DAC. The RS2 also has dual memory card slots each supporting up to 2TB of microSD cards.
The HiBy R2 has an MSRP of $479 and is currently available for pre-order at HiFiGo.com.
