New product
The TOPPING D90 III Discrete DAC features a fully discrete 1-bit PSRM module, ultra-low jitter, a ten-band parametric EQ, and high-resolution Bluetooth support, this DAC excels in delivering linear, distortion-free sound. It's ideal for those who want to hear every subtle nuance in studio-quality recordings, as well as enthusiasts who stream high-resolution audio and need flexible output options to pair with their systems.
Discrete 1-bit PSRM module
At the heart of the D90 III Discrete is its 1-bit DAC, a design that handles audio signals by processing them one bit at a time. Unlike conventional multi-bit DACs, which translate audio in larger data segments, potentially leading to quantization errors and added distortion, the 1-bit method toggles between only two states—on and off. This streamlined approach enables a more accurate and cleaner reproduction of the original audio. By simplifying the conversion process, the 1-bit design minimizes complexity and reduces unwanted artifacts, making it especially suitable for high-resolution audio playback.
Power supply
The D90 III Discrete DAC exemplifies high-end audio engineering with its robust, precision-crafted power supply. Its pure resistance output is specifically tailored to keep the analog signal stable and free from interference, even under conditions of rapid switching. This meticulous design ensures that signal integrity is maintained, which is crucial for an undisturbed listening experience.
With an impressive dynamic range of 130 dB and an outstanding signal-to-noise ratio of 131 dB, this DAC is capable of delivering music with remarkable clarity and depth. These specifications indicate that the D90 III Discrete will bring out the subtleties in your audio, ensuring both quiet passages and powerful peaks are conveyed without distortion, allowing listeners to enjoy the full range and texture of their music.
Ultra-low jitter
The D90 III Discrete is designed to keep jitter—the subtle distortions caused by timing errors—at an absolute minimum. Using a CPLD (Complex Programmable Logic Device) to optimize the clock signal, it reduces jitter to levels as low as -157 dB.
I/V conversion
TOPPING has redesigned the I/V (current-to-voltage) conversion circuit in the D90 III Discrete. This new circuit uses low-distortion op-amps and ultra-low noise components to ensure that your music retains its dynamics and depth.
Ten-band PEQ
The D90 III Discrete is indeed designed for audiophiles who want granular control over their sound output. The inclusion of a ten-band parametric EQ is a standout feature, allowing you to shape the sound precisely to suit your preferences or optimize it for different genres and listening environments.
High-res Bluetooth audio
With Bluetooth 5.1 and LDAC support, the D90 III Discrete offers wireless audio that doesn’t compromise on quality. The QCC5125 chip supports up to 96kHz/24-bit audio and a range of codecs like aptX-Adaptive and aptX HD, which gives you the freedom of wireless streaming without sacrificing sound quality.
Plug-and-play
The D90 III Discrete works seamlessly across a variety of platforms, including Windows, Mac, Linux, iOS, and Android. Its USB hardware supports up to PCM 768kHz/32-bit and DSD512, ensuring that you get the best possible sound, no matter the source. For Windows users, the included ASIO driver ensures smooth and reliable operation.
Flexible connections
The D90 III Discrete features both RCA single-ended and XLR balanced outputs, giving you the flexibility to connect to almost any system. With options for XLR 4V, XLR 5V, RCA 2V, and RCA 2.5V outputs, it’s easy to find the right setup for your gear. And with the ability to output to both connections at once, you can drive multiple systems simultaneously.
IIS input
The D90 III Discrete includes an IIS interface, which supports up to PCM 768kHz/32-bit and DSD512. This high-spec digital input provides the cleanest possible signal transmission, ensuring that your music comes through with all its detail intact.
Preamp mode
The D90 III Discrete's preamp mode is a fantastic feature for those looking to simplify their audio setup without sacrificing sound quality. By incorporating a volume control option, it allows you to connect directly to active speakers or a power amplifier, eliminating the need for a dedicated preamp. This not only reduces system complexity but also saves on cost and space, making it an excellent choice for streamlined setups.
With the D90 III, you're not just getting an efficient setup—you’re getting high-quality audio performance. Its discrete circuitry and high-quality components are likely designed to ensure precise volume adjustments and low distortion, maintaining signal integrity. This preamp mode makes it ideal for audiophiles and enthusiasts who want a clean, high-quality audio path from source to output with minimal gear.
12V trigger
With a 12V trigger input and output, the D90 III Discrete can sync with other devices in your setup for power on/off control. This makes managing your system simpler and more efficient.
