Descriptions:
> Re-defining Discrete 1-Bit Design
> The DX9 Discrete is TOPPING’s most advanced DAC/amp yet — a fully balanced reference unit built for absolute precision. At its heart lies a self-developed 16-element PSRM 1-bit DAC, bypassing the constraints of conventional chip-based solutions. This architecture offers unmatched linearity, tonal accuracy, and resolution, revealing micro-details buried deep in the noise floor. Paired with a six-channel discrete NFCA amplifier capable of 7,080 mW ×2 at 32 Ω and ultra-low noise, the DX9 delivers both refinement and raw power. Flexible PEQ, a sophisticated relay volume system, and extensive connectivity make it equally at home as a high-end DAC, headphone amplifier, or preamplifier in a flagship audio system.
> 1-Bit, Engineered In-House
> The PSRM DAC employs 16 discrete elements per channel to execute 1-bit decoding with nanosecond-level switching precision. By replacing off-the-shelf DAC chips with a fully controlled discrete architecture, Topping ensures full command over the conversion path. Performance at a glance: SNR: 131 dB, THD+N: <0.00006%, Crosstalk: –136 dB @ 1 kHz. This level of transparency preserves every nuance of the recording — from delicate transients to long decays — with impeccable channel balance.
> Jitter Elimination
> A CPLD precision clock system and dual-stage jitter suppression keep the digital stream exceptionally clean. The AK4118 receiver minimizes input jitter to <50 ps RMS, supporting PCM up to 768 kHz and DSD512. The result: sharp imaging, rock-solid stage stability, and precise timing.
> Power Meets Silence
> The discrete NFCA amplifier is engineered for maximum power without noise. Each channel operates independently, yielding up to 7,080 mW ×2 at 32 Ω, Noise floor: <0.5 µVrms (balanced), Output impedance: <0.1 Ω, Channel crosstalk: –133 dB. Whether driving sensitive IEMs or high-impedance headphones, the DX9 maintains total composure and black-background clarity.
> Relay Volume Control, Perfected
> The DX9 features a fully balanced hybrid relay volume control, merging relay switching with a resistor network for exact level adjustment. This design eliminates channel imbalance even at low volumes and maintains consistent stereo imaging.
> Refined I/V Conversion
> A proprietary I/V stage built from low-distortion op-amps and discrete components ensures that the DAC’s output is translated into voltage with maximum linearity and dynamics, preserving the timbre and space of the original recording.
> Customizable Sound with 10-Band PEQ
> The built-in ten-band PEQ allows precise tuning of frequency response. Each band supports adjustable frequency, Q-factor, and gain. Users can store multiple profiles via Topping’s software for different headphones, speakers, or listening preferences.
> Realistic Headphone Crossfeed
> The DX9’s crossfeed system uses HRTF and room convolution modeling to create a natural spatial field, reducing the typical “inside-the-head” headphone effect. A BS2B simplified mode is also available for more subtle crossfeed.
> 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.
> Premium Build
> The CNC-machined aluminum chassis with a glass top panel gives the DX9 a modern, elegant aesthetic. Ambient lighting adds subtle visual feedback. A programmable multifunction knob and 12 V trigger simplify system integration, while the aluminum remote ensures convenient control.
> Intuitive Aurora Interface
> The dual 2.0-inch color displays present FFT spectrum, VU meters, and playback data. The Aurora UI is clear, fast, and easy to use — no manual required.
