Gustard S26: Outstanding Network Player and Digital Audio Transport
The Gustard S26 is a network player and digital transport designed to significantly enhance the performance and quality of network audio playback. Every component, from the cooling system to the selection of hardware elements and the power supply circuit, has been carefully optimized to ensure smooth operation while minimizing noise and jitter in the output signal. With Gustard's optional 10MHz external clock generator and N18PRO audio switch, it can achieve ultimate quality.
Performance and Processor
The S26 is powered by a Ryzen 5 5600U processor, built on the Zen 3 architecture. The processor has 6 cores and 12 threads, with a base clock speed of 2.3 GHz, which can boost up to 4.2 GHz in turbo mode. This performance allows the S26 to ensure smooth operation under all conditions (e.g., handling DSD512 data files), providing unparalleled convenience in terms of user experience.
Efficient Cooling System
To avoid noise and interference, Gustard has chosen a passive heat pipe cooling solution that uses copper pipes. This guarantees efficient heat dissipation without the mechanical vibrations or noise caused by fans.
Internal Storage
The S26 is equipped with a 1TB NVMe SSD, allowing quick and high-quality access to your favorite tracks. Thanks to the speed of DDR4 RAM, storage operates smoothly. Additionally, if you need more storage, up to 4TB PCIe 3.0 SSD NVMe memory can be added (SSD sold separately).
Quality Power Supply
The S26's power supply is built on a 120VA OFC copper transformer. The current passes through a double bridge rectifier, capable of generating up to 800V DC with a capacity of 25A. The 400A starting current capacity ensures the system's efficiency and reliability. The 40800µF capacitors stabilize the power supply, providing continuous and uninterrupted power to the device.
The power supply for the various modules is provided through independent circuits, each equipped with low dropout regulators, ensuring that the power supply noise does not exceed 5µV.
Precise Timing: The "Soul" of Digital Audio
To perfectly synchronize the signal, the S26 sets the output frequency from a single clock. This clock controls the PCIe, network, and USB connections, ensuring system harmony and optimal stability. Gustard's proprietary GCLK-02 clock module uses phase-locked loop technology, providing exceptional accuracy with 1Hz locking performance. Additionally, for even greater accuracy, an external 10MHz clock can be connected via the 50Ω impedance BNC input.
Extended Compatibility
The Gustard S26 supports Roon Core and UPnP servers, making it integrable into a wide range of setups. The device is also compatible with Spotify Connect, Apple Airplay, and QQ Music services.
