Topping D900 Hi-Res DAC Preamp for Music Lovers with BT 5.1 Support and LDAC

Your Product'S Main Highlights

Self-Developed PSRM Module The D900 features a self-developed PSRM (Precision Switching Response Module) architecture. Composed of an ultra-high-speed switching logic array and precision voltage references, this module ensures a stable and noise-free purely resistive reference power design. This synergy between the reference power supply and switching logic enables the D900 to reproduce the original audio signal with exceptional fidelity, achieving harmonic distortion below -140dB and a SNR of 131dB.

Innovative I/V Conversion Circuit The D900 integrates a brand new, proprietary I/V (Current/Voltage) conversion circuit for superior audio performance. This circuit is built using low-distortion integrated operational amplifiers and ultra-low noise discrete components meticulously selected through rigorous testing. This design ensures the PSRM's output voltage remains pristine, delivering ample dynamics and a truly immersive sound experience.

Versatile Digital Input Array The D900 offers an extensive array of digital inputs designed for broad compatibility with virtually all source devices. Connect via USB-C, USB-B, optical, coaxial, Bluetooth, AES, or IIS-LVDS. Whether your source device is a computer, CD player, digital transport, or gaming console, the D900 can handle it with ease, allowing you to benefit from its high-performance DAC output and form the heart of a true high-end audio system.

Independent and Dedicated Preamplifier Circuit To enhance the D900's versatility, especially in floorstanding speaker systems, the device features an independent and dedicated preamplifier circuit. This circuit includes a high-precision volume control with 0.5 dB steps, enabling exceptionally smooth and refined volume adjustments for a comfortable listening experience.

Responsive Control Display The D900's control display is intuitive and user-friendly. A 2-inch full-color display provides clear real-time playback information. Three touch-sensitive buttons and a volume knob work seamlessly together for fast and intuitive adjustments. With a simple operation, users can easily switch between multiple display modes such as playback information, FFT spectrum, or VU meter—offering real-time feedback on audio performance. Additionally, the D900 offers nine background color choices, allowing you to customize the visual interface to match your personal preferences.

Ten-Band High-Precision PEQ Adjustment To provide a highly customizable audio experience, the D900 supports a ten-band high-precision parametric equalizer (PEQ) adjustment. Developed in-house, this new PEQ allows users to fine-tune the frequency, gain, and bandwidth of each band. Topping's advanced PEQ algorithm and desktop software offer precise control over the equalization settings, supporting up to PCM 192kHz/32bit sampling rates.

Ultra-Flagship Combo Experience An exceptional music experience requires not just the D900's powerful decoding capabilities but also the dynamic output of the A900 ultra-flagship headphone amplifier. This combination delivers a full range of headphone outputs, backed by industry-leading specifications and a minimalist control design, focusing on the pure beauty of music.
