The Audalytic DR70 is a high-end DAC designed for demanding audiophiles, combining a discrete R2R architecture with extended compatibility with high-resolution audio formats. Developed by Gustard, this model stands out with its R2R module, its native 1bit DSD converter and its dedicated FPGA, all synchronized by a CK-01 femtosecond oscillator for sound reproduction of exceptional precision and musicality. Whether listening to music via USB, coaxial, optical or Bluetooth 5.0, the DR70 establishes itself as a versatile and high-performance solution, suitable for home audio systems or high-end headphones.


The core of the DR70 is based on a discrete R2R module, providing PCM conversion of remarkable purity, without digital artifacts. For DSD formats, the DR70 integrates a native 1bit converter, capable of handling DSD64 to DSD512 streams without intermediate conversion to PCM, thus preserving the integrity of the original signal. This approach ensures a natural timbre, extended dynamics and resolution of micro-details, even on the most demanding recordings.

The custom FPGA of the DR70 manages signal processing logic, clock management and seamless switching between PCM and DSD modes, while the CK-01 femtosecond oscillator reduces jitter to an imperceptible level, improving stereo imaging accuracy and soundstage depth.
The DR70 easily connects to all your sources:
This versatility allows integration of the DR70 into various configurations, whether a wired system or a wireless setup.

The DR70 offers simultaneous RCA (2Vrms) and XLR (4Vrms) outputs, both at fixed level, for optimal compatibility with preamplifiers or active speakers. The output impedance is around 100Ω, ensuring a stable connection with most equipment.
The low-noise internal power supply is designed to minimize interference, but the DR70 also accepts an external 12-18V DC power supply for users wishing to further optimize performance.

The anodized aluminum chassis of the DR70 combines robustness and elegance. An LCD screen with adjustable brightness and an infrared remote control facilitate everyday use. The DR70 is compact and lightweight, integrating discreetly into any audio environment.
