Experience the ultimate beauty of music and a new depth to the art of playback from a device that exudes elegance.
The K series, the eternal icon of the Esoteric brand, is now updated to a new “Xs” edition.
The K-01 and K-03 are the Esoteric brand’s most iconic integrated Super Audio CD players.
First launched in 2010 before evolving to its second generation, the X edition, in 2014, it captivated people around the world with its incredible playback of music sources. These players have won more awards than any other Esoteric series, and have become the gold standard of digital players worldwide. And now this flawless series has evolved again into a third generation, the Xs edition. Every part of these players is made from luxurious materials and cutting-edge technology, from the new DAC platform used in flagship models like the Grandioso K1 and N-01 to the latest digital input parts and the ES-LINK Analog transmission method, creating a new page in the history of digital players.
The latest in a winning series
Carrying on the high-end concepts and technology from winning integrated players such as the Grandioso K1 and K-01Xs, the K-03Xs is what happened when we asked how far we could go, what heights we could reach with our performance model. The classic VRDS-NEO [VMK-3.5-10] drive mechanism contains a VS-DD circuit for smooth, quiet driving of the spindle. Developed based on the new DAC platform used in the Grandioso K1, the K-03Xs has a differential 4-circuit/channel dual mono DAC and Esoteric’s patented proprietary 34-bit D/A processing algorithm. The essence of our flagship model can be seen throughout the K-03Xs, from many of the latest devices to the DSD-compatible USB and core sound quality features and functions.
