Pre900

Full-Path Balanced Architecture
The Pre900 features a four-channel reference-grade amplification circuit with a true end-to-end balanced differential design from input to output. Left and right channels are physically isolated to minimise noise and electromagnetic interference, delivering exceptionally clean, transparent, and refined audio performance.

Independent Power Supplies
Digital and analogue circuits are powered completely independently to minimise crosstalk and interference at the source. Even during demanding dynamic passages, the Pre900 maintains an ultra-low noise floor with a silent background and exceptional detail retrieval.

0.1dB Precision Relay Volume Control
Using a relay array combined with a high-precision resistor network, the Pre900 achieves ultra-accurate 1,000-step volume adjustment with smooth and natural transitions between levels. Crosstalk remains below -150dB, ensuring perfect channel balance and accurate soundstage reproduction while preserving tonal consistency at every volume setting.

Focused on Music
The Pre900 inherits the clean and refined industrial design language of TOPPING’s flagship 900 series. Sharp yet understated lines create a cohesive appearance when paired with the matching components, reflecting TOPPING’s music-first design philosophy.

Powerful Headroom | Pure Signal Integrity
Delivering an impressive output swing of up to 69Vpp with gain up to 19.9dB, the Pre900 maintains ample headroom even during demanding transient peaks, helping preserve dynamic impact without clipping. Combined with a noise floor below 0.3uVrms, even the most delicate musical details are reproduced with outstanding clarity and transparency.

Performance Driven Engineering
The Pre900 is engineered to preserve the character of your source equipment while enhancing scale, dynamics, and control. Its transparent signal path allows the music itself to remain the focus of the listening experience.

Safe Volume Mode
A programmable safe volume feature automatically reduces the output level to a preset setting during power-on or input switching, helping protect both speakers and listeners from unexpected volume spikes.

Multiple Sources | Seamless Switching
The Pre900 includes three sets of stereo balanced combo inputs supporting both XLR and TRS connections. High-quality Neutrik combo sockets ensure stable and reliable connectivity for professional and high-end audio equipment.

Dedicated Balanced Output
A single pair of balanced XLR outputs ensures the most direct and optimised signal path possible. The Pre900 also supports 12V trigger input and output for synchronised power control with compatible upstream and downstream devices.

Designed for Flagship Systems
Together with the TOPPING D900 DAC and A900 headphone amplifier, the Pre900 completes a true flagship desktop Hi-Fi stack. Every stage of the audio chain is designed for uncompromising performance and precision.

Responsive User Interface
A 2.0-inch high-definition colour display with nine selectable background colours provides clear system information and customisation options. Three touch-sensitive buttons work alongside the multifunction control knob for intuitive operation, while display modes can be switched between playback information, FFT, and VU meter views.

Premium Infrared Remote Control
The supplied infrared remote is precision-machined from a single block of high-strength aluminium alloy and finished with fine sandblasting for a premium feel and elegant appearance.
