GUSTARD U26 USB Digital Interface - DSD 2048 PCM 1.536M, Dual rectifier bridges, OCXO and K2 clock system, CPLD digital signal shaping (Black)

Description

• The Precision Digital Bridge for High-End Audio Systems The Gustard U26 isnt a DAC or an amp. Its the digital bridge that ties your whole audio system together. Designed in collaboration with AmaneroTechnologies, it transforms USB input into ultra-precise digital output for your DAC through IIS, AES, or coaxial connections. With native DSD2048 and PCM 1.536MHz support, a temperature-controlled OCXO clock system, and independent power regulation, it delivers clean, stable, and timing-perfect data for the rest of your chain to shine.
• Filtering built for audiophiles The main filter capacitors deliver a total capacity of 80,000F. That means robust, stable current delivery no matter how demanding your DAC or amplifier might be. Gustards discrete power design pairs metal-cased transistors with TO-3 heat-sink housings, maintaining cool operation even when the night slips away from you.
• Dual rectifier bridges The U26 uses dual rectifier bridges with metal heat sinks rated for 800V DC reverse voltage and 25A current. Forward voltage drop is a mere 1.1V at 12.5A, with a surge current capacity of 400A. In short: efficient conversion, low heat, and dependable long-term performance.
• OCXO and K2 clock system At its core, a temperature-controlled OCXO crystal oscillator and K2 ultra-low-noise PLL clock generate dual clock signals98.3040MHz and 90.3168MHzwith 0.1ppm stability. These clocks suppress jitter at the source, keeping your DACs conversion process free from timing errors. The result is sharper transient response, improved imaging, and a blacker noise floor.
• CPLD digital signal shaping A custom programmable logic device re-shapes IIS signals after isolation to remove any residual jitter. Think of it as signal reconstruction at the digital level. Your DAC receives a pristine, phase-accurate feed that unlocks its full potential.
• Full-format PCM and DSD support The U26 handles PCM up to 32-bit/1.536MHz and DSD up to DSD2048. Whether youre listening to standard 44.1kHz CD rips or ultra-high-res masters, it passes bit-perfect data to your DAC with clocking stability that keeps music grounded and lifelike.
