Topping DX9 Discrete Flagship 1-Bit Fully Balanced Desktop DAC / Amplifier

1-bit done right

Topping’s proprietary PSRM DAC architecture uses 16 discrete elements per channel to perform 1-bit decoding with nanosecond-level switching. By eliminating off-the-shelf DAC chips, the DX9 Discrete controls every step of the digital-to-analog process. 



Balanced power from end to end

The DX9 Discrete’s six-channel discrete NFCA amplifier is built for demanding headphones. Each channel operates independently, producing up to 7,080mW ×2 at 32Ω with noise below 0.5µVrms (balanced) and 1.1µVrms (single-ended). The sound stays quiet, composed, and distortion-free no matter how far you turn the knob.



Connections for every occasion

With eight digital inputs—USB, Bluetooth, two optical, two coaxial, AES, and IIS—the DX9 Discrete fits into any listening chain. IIS supports up to 768kHz PCM and DSD512. USB uses the XMOS XU-316 processor and Thesycon driver for bit-perfect playback on Windows and plug-and-play compatibility with other systems.



Output options your way

Choose between headphone, line, or preamp output—or run everything at once with All Output Mode. Outputs include XLR, RCA, 6.35mm, 4.4mm, and XLR-4, all using NEUTRIK connectors for reliable, professional-grade performance.



Wireless that holds its own

The integrated Qualcomm QCC5125 Bluetooth 5.1 module supports LDAC, aptX Adaptive, aptX HD, aptX, AAC, and SBC. Stream lossless audio from your phone or laptop with high-resolution clarity and low latency.



Tune to your taste

The built-in ten-band high-precision PEQ lets you tailor your frequency response exactly how you like it. Adjust gain, Q-factor, and frequency for each band, or import target curves through Topping’s software. Save multiple profiles for headphones, speakers, or genres.
