Ready to hear it all?
The TOPPING D90 III Discrete DAC is engineered for audiophiles and professionals who demand absolute precision and transparency in their audio. Featuring 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: precision on every channel
At the core of the D90 III Discrete is its 1-bit DAC, a design that processes audio signals one bit at a time. Traditional multi-bit DACs convert audio in larger chunks, which can introduce quantization errors and increase the risk of distortion during conversion. In contrast, the 1-bit approach switches between only two states—on and off—resulting in a much cleaner and more faithful reproduction of the original audio signal. By simplifying the conversion process, the 1-bit design reduces complexity and potential artifacts, making it ideal for high-resolution audio.
