Four years after the release of the K-01—the world’s leading all-in-one digital player—the new K-01X debuts as a more compact version of Esoteric’s flagship Grandioso model. Utilizing the same type of highly rigid chassis construction as the Grandioso and a similar four-transformer power supply, it integrates the Grandioso P1’s high-precision VRDS-NEO “VMK-3.5-20S” turntable with two independent monaural DAC units derived from the Grandioso D1 design, each configured with a parallel array of 8 individual converters, which are summed to optimize linearity and minimize noise.
Electronic circuitry has also been further improved with the latest technologies, including a new AK4495S DAC IC, an advanced 35-bit D/A processing algorithm, an HCLD buffer amp, a DSD-compatible USB interface, and a large, low phase noise clock, all ensuring the K-01X achieves the absolute pinnacle of sound quality.
