Elevate your audio system with a preamplifier born from 23 years of masterful tube craftsmanship. This preamp redefines value by incorporating a true, end-to-end balanced architecture and features typically found in cost-no-object components. From its obsessive power supply to its reference-level circuit, every element is designed to deliver unparalleled purity, a vast, silent soundstage, and an emotionally engaging musical experience.
A great preamplifier is born from a great circuit. Our design pays homage to the legendary topologies of world-renowned brands like Audio Research (ARC) and Cello (诗醉). After years of continuous refinement, we have perfected this circuit to achieve our signature sound, defined by:
Zero Negative Feedback Design: We eliminated global negative feedback to achieve a more transparent, open, and immediate presentation. The music breathes with a palpable sense of "air" and ambiance.
Expansive & Authoritative Sound: Experience deep, articulate bass, sparkling and extended highs, and a rich, natural mid-range with a lifelike body perfect for vocals and instruments.
Precise Soundstage & Imaging: The soundstage is wide and deep, with pinpoint accuracy in the placement of performers, creating a truly immersive listening experience.
The quality of your power determines the quality of your sound. This preamp integrates a sophisticated balanced isolation power supply—a component that often costs hundreds of dollars on its own.
Quad-Transformer Design: Separate power transformers for high voltage, filament, and digital control circuits ensure no cross-interference.
Pure Power: The system starts with EMI filtering and uses balanced power isolation technology to cancel out grid noise, resulting in an exceptionally low noise floor and an "inky-black" background.
Tube Rectification: A 6Z4 tube rectifier (compatible with 6X4) provides a smooth and natural sound signature, filtered by a high-quality Siemens EPCOS capacitor matrix.
Forget the signal degradation and channel imbalance of traditional potentiometers. Our advanced R2R resistor ladder, controlled by high-speed relays, ensures the audio signal passes only through a network of precise, fixed resistors. This results in:
Significantly more musical detail and improved dynamics.
Perfect channel balance at any volume level.
Long-term reliability and a satisfying tactile feel.
Designed to be the command center for any complex audio setup:
6 Inputs: 3x Balanced (XLR) and 3x Single-Ended (RCA).
6 Outputs: 3x Balanced (XLR) and 3x Single-Ended (RCA).
Flexible Output Modes: Run a single output or all 6 outputs simultaneously—perfect for bi-amping or driving multiple power amps and subwoofers without impedance issues.
We've combined this reference-level audio circuit with a modern MCU control system for the best of both worlds.
Large LCD Display: A high-contrast, interference-free screen clearly shows all settings.
Full Remote Control: Power, volume, mute, input/output select, and screen brightness at your fingertips.
Smart & Safe: Enjoy features like a soft-start with mute delay (no pops or thumps) and shutdown memory that recalls your last used settings.
