TOPPING D90III DISCRETE

Revolutionary PSRM Technology for Ultimate Fidelity
The TOPPING D90III Discrete features a cutting-edge 16-phase PSRM module for both the left and right channels. This fully discrete 1-bit DAC uses advanced architecture with ultra-fast switching logic arrays and a precision voltage reference to ensure an accurate and unaltered audio signal. After extensive testing of over 20 different components, we selected the best combination to minimize any disturbance to the voltage reference. With a signal-to-noise ratio (SNR) of 131dB and a dynamic range (DNR) of 130dB, the D90III Discrete delivers unparalleled performance and reliability, making it the perfect choice for serious audiophiles.

Ultra-Low Jitter for Pristine Audio
Using a CPLD (Complex Programmable Logic Device) to process the clock signal, the D90III Discrete achieves exceptional jitter rejection. With jitter as low as -157dB, the D90III Discrete ensures a stable, clean sound that meets the highest industry standards, capturing even the most subtle nuances in your music.
Next-Generation I/V Conversion Circuit
The proprietary I/V conversion circuit in the D90III Discrete is designed for maximum audio quality. With low-distortion integrated operational amplifiers and ultra-low noise discrete components, this innovative design ensures pristine voltage output, resulting in dynamic, immersive sound that takes your listening experience to new heights.

Precise 10-Band PEQ Adjustment
Topping¡¯s new 10-band PEQ adjustment software allows you to fine-tune your audio with customizable frequency bands. You can import and adjust target curves to match your preferences, ensuring a personalized sound signature for any listening environment.
Wireless Hi-Res Audio with LDAC Support
Equipped with the QCC5125 chip, the D90III Discrete supports Bluetooth 5.1 and a variety of audio encodings, including LDAC, aptX HD, and more. Experience wireless high-resolution audio with up to 96kHz/24bit quality, providing a listening experience that rivals wired connections.

llS-Ultra-high Specification Signal Input Interface
The D90III Discrete is equipped with a customized digital audio transmission interface that is not HDMI but supports up to PCM768kHz/32bit and DSD512 native formats. The DAC¡¯s llS interface needs to match the llS interface definition of the digital interface. The D90III Discrete supports the following llS modes: DSD FLAG 15, DSD FLAG 14, IIS DSDR LRCLK, IIS DSDR DATA, IIS PHASE STD, and IIS PHASE REV. It is compatible with most digital interfaces, ensuring efficient integration with various audio systems.
Multiple Output Modes for Maximum Flexibility
The D90III Discrete offers both balanced XLR and single-ended RCA outputs, along with selectable output voltage levels. Whether you need to adapt to different setups or achieve even higher performance with XLR 5V and RCA 2.5V outputs, this DAC gives you flexibility and control over your system.

Preamp Mode for Direct Connection to Active Speakers
With its built-in preamp mode, the D90III Discrete allows you to connect directly to active speakers or amplifiers, eliminating the need for a separate preamp. Adjust the volume with the included Bluetooth remote for a convenient, streamlined setup.
12V Trigger for Seamless Integration
The D90III Discrete is equipped with 12V trigger input and output, enabling synchronized power on/off functionality with other connected devices. This makes it easier to integrate the DAC into your existing audio system for a more cohesive experience.
Bluetooth Remote for Easy Control
Enjoy full control from a distance with the 2.4G Bluetooth remote, which works seamlessly through obstacles for effortless operation.
