Fully Balanced Pre-Amplifier
Topping - Pre900
Pure in Form, Pure in SoundThe Topping Pre900 is a high-end preamp with full-path balanced architecture, featuring a four-channel reference-grade amplification circuit. It implements true end-to-end differential design from input to output. Left and right channels are physically isolated to the highest degree, effectively suppressing noise and electromagnetic interference, delivering exceptionally pure and pristine sound.
Amazing Features
• Four-channel fully balanced achitecture
• 0.1 dB precision relay volume control
• 3 X BAL(XLR/TRS) stereo inputs
• Independent power supplies
• <0.00003% THD @20-20kHz
• -159dB channel crosstalk
• Three gain settings
• 12V trigger in/out
• 151 dB DNR
World-Class Quality
independent power suppliesDigital and analogue circuits are powered completely independently, minimizing crosstalk at the source. Even at high dynamic output, the noise floor remains imperceptible, the background pitch-black, and every musical detail vividly alive.
0.1 dB precision relay volume controlRelay array combined with a high-precision resistor network achieves 1,000-step volume adjustments, with each stop switching smoothly and naturally. Crosstalk stays below -150 dB, ensuring that the left and right channels remain perfectly synchronized at any volume. The soundstage is accurately reproduced, and throughout the entire adjustment process, only the volume changes whilst the tonal quality stays consistent.
focused on musicPre900 inherits the clean, flowing edge-line design of TOPPING's flagship 900 Series. Its lines are sharp yet restrained, creating a seamless visual harmony when stacked with the complete system - a clear expression of music-first design philosophy.
powerful headroom, pristine signalPre900 delivers an impressive output swing of up to 69 Vpp, with gain reaching 19.9 dB. Even during explosive transient peaks, it maintains ample headroom without clipping, allwing for a more powerful and dynamic listening experience. With a noise floor of <0.3 µVrms, Pre900 can fully amplify even the most delicate signals without adding audible noise, preserving the integrity, stability, and transparency of the sound.
Driven by Performance
Proven by MeasurementWith the Pre900 in your system, what you hear is not the sound of the pre-amplifier, but the sound of the source itself - only with greater presence, tension, and composure.
Full Audio Potential
safe volume modeSet a preferred safe volume level for the Pre900. Whether during power-on or input switching, the device automatically lowers the volume to your preset safe level, protecting you from unexpected loud bursts.
multiple sources, seamless switchingPre900 features three sets of stereo balanced combo inputs (XLR & TRS), offering broad compatibility with professional equipment and various audio sources. All input connectors use Neutrik combo sockets for stable, reliable connections, meeting the demands of high-standard audio systems.
focused output for one dedicated systemPre900 is equipped with only one pair of XLR balanced outputs to ensure the most optimized signal path. It also supports 12V trigger input and output, allowing it to power on and off in sync with your upstream and downstream devices for one-touch system control.
made for your flagship systemTogether with the ultra-flagship D900 DAC and A900 headphone amplifier, Pree900 completes a true flagship stack. From digital to analogue, from signal processing to powerful drive, every stage is elevated - bringing you a world-class listening experience.
responsive controlEquipped with a 2.0-inch high-definition colour display and 9 selectable background colours, it adapts perfectly to your visual preferences. The three touch buttons on the right work seamlessly with the multi-function knob. You can also switch display modes with a single touch (playback information / FFT / VU meter).
infrared remote controlThe main part of remote control is crafted from a single block of high-strength aluminum alloy using precision CNC machining, followed by the fine sandblasting for a refined finish.
