The Wanda DAC (Digital-to-Analog Converter) has gained immense popularity in the audiophile community for its exceptional sound quality and advanced technological capabilities. This article delves into the intricate workings of the Wanda DAC internals, exploring its architecture, circuitry, and functional components.
At the heart of the Wanda DAC lies a dual-mono configuration, which separates the left and right audio channels into two independent signal paths. This isolation ensures minimal crosstalk and enhances stereo imaging.
The Wanda DAC employs an asynchronous USB interface that eliminates jitter and ensures a stable data transfer from the source device. This allows for accurate timing and precise signal reproduction.
The centerpiece of the Wanda DAC is the ESS Sabre ES9038Q2M DAC chip. This high-performance DAC features 8 channels, 130dB of dynamic range, and low total harmonic distortion (THD+N).
A femtosecond crystal oscillator provides ultra-precise timing signals that minimize jitter and improve audio fidelity.
The analog output stage utilizes high-quality operational amplifiers (op-amps) to drive the audio signal. These op-amps provide low noise and high gain, ensuring clean and accurate reproduction.
The Wanda DAC relies on a linear power supply that filters out noise and provides a stable voltage to the sensitive circuitry.
The power supply employs multiple voltage rails to isolate digital and analog components, reducing interference and improving sound quality.
The Wanda DAC supports a wide range of PCM (Pulse Code Modulation) and DSD (Direct Stream Digital) formats, including up to 32-bit/384kHz and DSD512.
The DAC's balanced XLR and single-ended RCA outputs produce exceptionally high-quality audio characterized by a wide soundstage, accurate imaging, and detailed transients.
