Back and better than ever

Our best-selling desktop DAC is back, and it’s better than ever. Boasting two state-of-the-art ES9039SPRO DAC chips, this fully-balanced decoder pushes the limits of fidelity with 135dB SNR and <0.000045% THD+N. With an upgraded Bluetooth 5.1 chip, your wireless options are faster and more stable than ever. Plus, an all-new CPLD reduces jitter even further, and a 12V trigger lets you chain all of your TOPPING devices for greater convenience. 

Dual ES9039SPRO chips: peak performance in every note

The heart of the D90 III beats with two ES9039SPRO chips. This dual-chip arrangement means each audio channel operates independently, achieving a higher Signal-to-Noise Ratio (135dB), dynamic range, and a significant reduction in distortion (<0.000045% THD+N). 

Advanced CPLD processing: jitter-free audio

The innovative use of CPLD (Complex Programmable Logic Device) in the D90 III ensures astounding jitter rejection. This advanced processing of the clock signal refines the digital signal to an unprecedented level, offering a jitter as low as -160dB across various inputs. 

New I/V conversion circuit

The brand-new I/V conversion circuit in the D90 III is a leap forward in audio reproduction. This circuit design stands out by offering lower distortion, reduced noise, and minimal spatial footprint, pushing the limits to extract every bit of performance from the DAC chip. 

High-resolution wireless audio: Bluetooth 5.1

Equipped with a QCC5125 Bluetooth 5.1 chip, the D90 III supports various high-resolution codecs, including LDAC, aptX-Adaptive, and more. This feature allows wireless transmission of high-quality audio up to 96kHz/24bit, far beyond the CD-level experience.

Universal compatibility and ease of use

The D90 III is a breeze to use with its wide compatibility range. It supports various operating systems like Windows, Mac, Linux, and iOS/Android. For Windows ASIO, a simple driver setup is all it takes. The device's USB hardware is based on XMOS XU316 and Thesycon drivers, ensuring stability and reliability.

Versatile output modes

Choose between balanced XLR output and single-ended RCA output. The D90 III adds more versatility with XLR 4V and RCA 2V outputs for broader device adaptation, and XLR 5V and RCA 2.5V for pushing performance to new extremes.
