What Gustard’s Audalytic DR70 R2R Streamer DAC Tells Us About High-End Audio Crossover
Gustard’s Audalytic DR70 is a significant departure from conventional digital signal processing in the world of high-end audio. This Resistive-to-Resistive (R2R) Digital-Analog Converter (DAC) uses a unique implementation of R2R DAC technology, which sets it apart from more conventional DAC designs like those using Sabre or ESS chips.
What is R2R DAC Technology?
At its core, R2R DAC technology employs resistive loading to convert digital signals into analog audio. This process involves a series of resistors that progressively divide down the signal until it reaches a point where the resolution can no longer be improved. By doing so, R2R DACs sidestep complex and expensive circuitry required by other technologies, resulting in a cleaner approach to digital-to-analog conversion.
Gustard’s Audalytic DR70: A High-End R2R DAC
The Gustard Audalytic DR70 is an exemplary embodiment of this technology. With its built-in headphone amplifier and support for both digital and analog inputs, it offers flexibility for audiophiles seeking to optimize their high-end systems. Its proprietary “Dual-Linear” architecture enables the use of discrete resistors rather than thin-film resistors, further reducing noise and distortion.
How Does R2R DAC Technology Address Audio Crossover?
One of the most pressing challenges facing high-end audio designers is crosstalk and intermodulation distortion in multichannel systems. When multiple digital signals are transmitted simultaneously, they can bleed into adjacent channels, resulting in sonic degradation and loss of detail. Traditional DAC technologies often rely on complex filtering and equalization techniques to mitigate these effects, which can introduce their own set of problems.
R2R DACs operate under a different paradigm – by isolating each channel through individual resistive loading, they effectively eliminate crosstalk and minimize intermodulation distortion. This approach is particularly relevant in high-end audio systems where multiple digital signals are transmitted simultaneously.
The Role of Resistive Loading in High-End Audio
The precise implementation of resistive loading is critical to an R2R DAC’s performance. Gustard’s DR70 boasts a “Pure-Delta” resistor network, carefully selected for its exceptional linearity and precision. This approach allows for maximum signal accuracy and minimal loss due to the conversion process.
Comparison with Other DAC Technologies
While R2R DACs have their advantages, they are often pitted against more conventional technologies like Sabre and ESS. Proponents of R2R DACs argue that these benefits come at the cost of increased complexity and price. In direct comparison, an R2R DAC like Gustard’s DR70 may not match the sheer resolution of a high-end Sabre chip but will make up for it in terms of sonic purity.
Implications for High-End Audio Systems
For audiophiles looking to upgrade their systems or transition into high-end audio, an R2R DAC like the Gustard Audalytic DR70 offers a compelling alternative. By sidestepping complexities of traditional digital signal processing, it allows users to reap benefits such as reduced noise floor and improved dynamics.
Real-World Applications: Can R2R DACs Enhance Your Listening Experience?
The real-world implications of adopting an R2R DAC like Gustard’s DR70 are evident in the feedback from audiophiles who have chosen this path. One common observation is a reduction in digital “hash” and noise artifacts, allowing for more immersive musical experiences. Another is an increased sense of spatial awareness – subtle cues and textures that were previously lost become palpable and lifelike.
In essence, the Gustard Audalytic DR70 offers a refreshingly uncomplicated approach to high-end audio processing that deserves attention from enthusiasts seeking to optimize their systems for maximum sonic pleasure.

The Gustard Audalytic DR70's R2R DAC technology is an intriguing solution for high-end audio enthusiasts, but its limitations shouldn't be overlooked. While this approach may excel in reducing noise and distortion, it can also introduce new variables into the system, such as thermal stability issues with discrete resistors. Furthermore, the proprietary "Dual-Linear" architecture, although optimized for low noise, might not be as scalable or cost-effective for larger systems or mass production. A more nuanced exploration of these trade-offs would provide a clearer picture of R2R DAC's potential in high-end audio.
