Now on Apos: Gustard R30 Fully-Discrete R2R Network Streaming DAC
Gustard R30 Fully-Discrete R2R Network Streaming DAC
With digital-to-analog converters (DACs), the conversation often circles around chipsets. AKM, ESS, Cirrus Logic: the usual suspects. The Gustard R30 takes a different path. It’s built around a fully-discrete R2R ladder network, a design that trades integrated circuits for carefully matched resistors. In layman's terms, that means a sound signature with a more natural tone and "analog tone" than is often found with D/A chips.
What makes the R30 different
The R30 is more than just a DAC. It's a hub. In addition to converting your digital music into analog, it doubles as a streamer and preamp. Whether you’re running it into powered monitors, a headphone amplifier, or a full two-channel system, the R30 is flexible enough to slot right in.
Thanks to built-in network streaming, you don’t need a separate streamer to enjoy lossless audio. The R30 supports Roon, DLNA (Digital Living Network Alliance), and AirPlay, giving you multiple ways to get your music into the system. Fewer boxes, fewer cables, less hassle overall.
Inputs and outputs for any system
The R30 covers your bases. You get multiple digital inputs—USB, coaxial, optical, and I²S (Inter-IC Sound, a digital audio interface often used for high-end transports). Analog output options include both balanced XLR and single-ended RCA.
Clocking and isolation
Good conversion isn’t just about the DAC stage, it’s also about timing. The R30 uses dual high-precision femtosecond clocks to keep jitter (timing errors) extremely low. Power supplies and circuit layouts are designed for noise isolation, keeping interference out of your signal path.

Who it’s for
If you want a DAC that doesn’t rely on mass-produced silicon, the Gustard R30 is worth a look. It’s for listeners who care about tonal naturalness, but also want modern conveniences like network streaming and flexible I/O. You can drop it into your system as the centerpiece without stacking more gear than you need.
