The Unison Research Unico CDUno delivers exceptional sound reproduction by prioritizing low distortion and high signal-to-noise ratios. Its meticulous design fosters a pure class A operation, ensuring audio fidelity throughout various digital playback formats.
The Unico CDUno integrates a high-spec DAC with a CD mechanism optimized for various audio formats and sampling rates, ensuring a wide dynamic range and low total harmonic distortion. It employs a 12AU7/ECC82 double triode in pure class A configuration for the audio stage, followed by a solid-state discrete analog buffer that maintains low output impedance for superior audio performance. The DAC is powered by a robust architecture featuring multiple stabilized power supply rails, which minimizes noise and crosstalk between digital and analog sections, thanks to advanced filtering and regulation techniques. The implementation of an ESS Sabre DAC ES9018K2M, known for its jitter elimination capabilities and outstanding signal-to-noise ratio (125 dB), advances the CDUno's ability to deliver pristine audio with fidelity to the original recording across a diverse range of digital and analog formats.
