TOPPING D90SE Updates to D90 III Discrete

TOPPING has introduced an array of highly-regarded DACs, ranging from budget-friendly options to top-of-the-line models. Today, they are set to unveil the successor to the D90SE, named D90 III Discrete, priced at $999. As its name suggests, the D90 III Discrete is a 1-bit DAC constructed using discrete components. Let's delve into the details.

The D90 Ill Discrete features 16-phase PSRM modules for each of the left and right channels. It uses an advanced architecture consisting of an ultra-fast switching logic array and a precision voltage reference, which is the core of the PSRM circuit. After rigorous testing of more than 20 device types and configurations, TOPPING selected the best combination, which not only switches at amazing speeds but also maintains the integrity of the original signal. The components are selected to minimize any disturbance to the voltage reference power supply, thus ensuring excellent performance and reliability.

The power supply design of the voltage reference is also very important and is crucial to ensure the accuracy of the analog output. The digital logic switches switch at the nanosecond level with sharp rising and falling edges, which may generate noise that interferes with the analog signal. To solve this problem, TOPPING pioneered the design of a stable, noise-free pure resistance output power supply, which enables each DAC component to achieve extremely precise output. Resulting in a excellent reproduction with amazing fidelity, achieving 130 dB DNR and 131 dB SNR.

D90 III Discrete achieved incredible jitter rejection using CPLD to process the clock signal and optimize the digital signal. In the jitter test commonly used by current measurement websites. It has excellent jitter performance, with jitter as low as -157dB. 

A brand new I/V conversion circuit is designed for higher quality audio reproduction. The proprietary I-V circuit is composed of low-distortion integrated operational amplifiers and ultra-low noise discrete components carefully selected after repeated testing. This ensures that the voltage output of the PSRM remains pristine, providing ample dynamics and an immersive sound experience.

D90 Ill Discrete has reached a new height in music reproduction, with THD+N < 0.00006%. All the notes captured at the recording site are perfectly reproduced, and every detail of the music is carefully reproduced.

D90 III Discrete features a brand-new developed PEQ adjustment, which supports ten customizable frequency bands. The brand new PEQ algorithm and desktop software allow you to fine-tune the frequency, gain, and bandwidth of each PEQ band. The software supports the import of target and original curves as well as the compensation of curves using target curves. It can also save multiple profiles for easy switching.

Equipped with QCC5125 chip, D90 Ill Discrete supports Bluetooth 5.1 and can support up to 96kHz/24bit. Also it fully supports LDAC/aptX-Adaptive/ aptX/aptX HD/AAC/SBC and other audio encodings, allowing high-quality audio to be transmitted wirelessly to provide a music experience beyond CD level.

In addition to the fixed output level DAC mode, the D90 Il Discrete also has a "preamp" mode. In preamp mode, you can adjust the output volume of D90 Ill Discrete, then connect it directly to a pure amplifier or active speaker. That saves the cost of a pre-amplifier. You can also use the D90 Ill Discrete remote control to control the volume, which is further convenient for use. Additionally, Pair the D90 Ill Discrete DAC with the A90 Discrete headphone amplifier for a fully discrete balanced setup that can drive nearly any headphone to reach a superior quality.

D90 III Discrete features many offering you might need, it's a great addtion to TOPPING lineup. Now, time to get your own perfect desktop. As always, If you have any questions, suggestions, or comments are welcome, feel free to contact us for the discount details or anything else, live chat with our CS team, or email us directly at support@shenzhenaudio.com, as well easy to find us on social accounts.
