Gustard R26 R-2R DAC

GUSTARD R26 R-2R DAC

The Gustard R26 is the original discrete R-2R network streaming DAC that established Gustard's current resistor-ladder platform. It combines a fully balanced discrete conversion architecture with Ethernet streaming, Bluetooth, I²S, USB and external 10MHz clock support in a substantial dual-transformer chassis.

DISCRETE BALANCED R-2R ARCHITECTURE

Instead of an off-the-shelf delta-sigma DAC chip, the R26 uses proprietary high-precision resistor ladders for PCM conversion. Its analogue low-pass and output stages are also built from discrete components, while separate power sections and two linear transformers supply the digital and analogue circuitry.

HIGH-RESOLUTION DIGITAL CONNECTIVITY

USB, HDMI-format I²S and Ethernet support PCM up to 32-bit / 768kHz, Native DSD512 and DoP up to DSD256. AES/EBU, coaxial and optical inputs support PCM up to 24-bit / 192kHz and DoP64. The R26 also provides Bluetooth 5.0 with LDAC, aptX HD and other major codecs.

NETWORK STREAMING & PRECISION CLOCKING

The built-in Ethernet renderer supports Roon Bridge, AirPlay, UPnP and HQPlayer NAA playback. Gustard's K2 clock synthesizer manages internal timing, while a 50Ω BNC input allows connection of a compatible external 10MHz reference clock.

FINAL BLACK UNIT AVAILABLE

This listing is for the original first-generation R26, not the newer R26 II. Production of the original model has ended and Audiophoria has one new Black unit remaining. For customers wanting Gustard's latest R-2R platform, the current R26 II is the direct successor.
