Cen.Grand 9i-92SA III "Golden Thrush" – Premium Desktop DAC, Headphone Amplifier, and Preamplifier
The Cen.Grand 9i-92SA III "Golden Thrush" is a high-end, multi-functional audio component designed for audiophiles seeking uncompromising performance. This desktop DAC, headphone amplifier, and preamplifier delivers exceptional clarity, dynamic range, and versatility, making it ideal for high-resolution listening setups.
Key Features
Dual ESS ES9038Pro DAC
The 9i-92SA III features two ESS ES9038Pro DAC chips, one for each channel. These chips incorporate eight parallel DAC units per channel, resulting in ultra-low noise and distortion, as well as enhanced musical detail.
Benefits of Parallel DAC Configuration
- Improved Signal-to-Noise Ratio (SNR): Averaging multiple DAC outputs reduces random noise, creating greater clarity.
- Lower Distortion (THD+N): Internal discrepancies among chips are balanced out, minimizing harmonic distortion.
- Expanded Dynamic Range: Higher DAC count allows more precise signal conversion, preserving details even at low volumes.
- Refined Sound Characteristics: The result is a smooth, highly detailed, and controlled audio output—particularly beneficial for complex and high-dynamic-range recordings.
High-Resolution USB Interface
The second-generation XMOS XU208 USB processor with FPGA digital processing supports:
- PCM 32-bit / 384 kHz
- Native DSD512
Advanced USB isolation technology eliminates computer-generated noise, improving the purity of the signal.
SPDIF Inputs
The AK4118 digital interface supports:
- Coaxial, optical, and AES/EBU inputs
- PCM 24-bit / 192 kHz
- DSD64 (DoP)
Headphone Amplifier with Four Output Modes
The 9i-92SA III features four configurable headphone amplifier modes to optimize performance across various headphone types:
- Normal – Ideal for high-sensitivity headphones and IEMs
- Balanced (BTL) – True differential mode for high-impedance headphones (e.g., Sennheiser HD800S)
- Active Ground (Virtual GND) – Simulated grounding for warmer, more harmonic sound
- Parallel – Enhanced current drive for medium-impedance headphones
Preamplifier Functionality
Designed with discrete components, the preamplifier includes:
- Stereo RCA and XLR inputs and outputs
- Infrared remote control
Output and Connectivity
Headphone Outputs
- 6.35mm single-ended jack
- 4-pin XLR balanced output
Volume Control
The PGA2311 chip with microcontroller (MCU) management offers:
- Fine-step volume control
- Adjustable range from -70 dB to 0 dB
