CaracterísticasTaking Sound to the X Dimension
X is the unknown. “X” in a model name symbolizes the ultimate advancements of technology, craftsmanship and creative commitment.
The K-01 and K-03 have won high acclaim as leaders of Esoteric’s line of all-in-one Super Audio CD players, and their extraordinary ability to reproduce the essential qualities of a musical performance continues to enthrall listeners to this day.
Now, a new “X” inherits that solid pedigree and further refines these qualities in the new K-01X and K-03X Super Audio CD players. Concentrated beauty in an all-in-one form is a hallmark of Esoteric’s flagship Grandioso models.
The philosophy and technologies found in these high-end digital players reveal a new dimension of sound appreciation unlike anything you have ever experienced before.
A New Pinnacle of Sound Quality
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.
