Gustard introduces the DAC-R26 , a completely unique digital-to-analog converter. It uses R2R architecture using very high quality discrete components that are perfectly optimized to deliver exceptional sound. Practical, it features not only full connectivity, but also Bluetooth and network connectivity, allowing you to control the reading of your music from a distance. All this is integrated into a modern and luxurious chassis of the most beautiful appearance.

The R2R discrete
DAC used in the Gustard DAC-R26 relies on high-precision resistor switching to perform digital-to-analog conversion. Compared to delta-sigma DAC, R2R provides cleaner and more natural sound. More expensive and demanding design, but it provides unparalleled performance.

Synchronous Clock Technology
The principle of this technology is that the original clock generator is used only as a reference frequency. The clock signal provided by the ultra-low noise K2 module is then used to replace the original clock signal. This way, the original clock can be dispensed with and the DAC uses only the extremely accurate femtosecond clock, so the conversion is independent of the original clock. Thus, this architecture can significantly reduce jitter.

LPF
Gustard DAC-R26 low-pass filter parameters have been optimized. The use of discrete components rather than integrated circuits allows each element to be independently adjusted to achieve the best operating conditions.

Network Connectivity
The DAC-26 has network connectivity thanks to its RJ45 port. It supports UPnP, AirPlay and Roon Bridge protocols. This will allow you to enjoy music stored on your network devices.

Bluetooth 5.0
In addition to network connectivity, the DAC-26 is also equipped with a Bluetooth 5.0 receiver chip. This makes it possible to control the reading of your music remotely, directly from your smartphone.

XMOS USB Interface
Another high quality component built into the DAC-26 is its XMOS USB interface. It allows it to decode high-resolution audio streams through the USB input, up to PCM 32bit 768kHz and DSD512.
