Since its inception in 1987, Esoteric has been at the forefront of innovation as a high-end audio brand from Japan, continually pushing the boundaries of high quality sound reproduction. The Esoteric brand is known for its outstanding acoustic engineering that has sustained its reputation and prestige, its massive investment without regard to cost, its “museum quality” craftsmanship, and its beautiful designs worthy of music reproduction.
Esoteric has brought a number of highly original innovations to the world of high-end audio, including the legendary VRDS-ATLAS Super Audio CD transport mechanism, Master Sound Discrete DAC and Master Sound Discrete Clock with proprietary discrete circuits; it is no exaggeration to say that Esoteric’s history is synonymous with digital playback innovation in high-end audio.
Finally, the SE versions of the K-01XD and K-03XD are now available with new discrete clock technology and improved analog circuitry in the DAC. We are proud of our brand and always strive for the best sound.
The SE models we are releasing this time reflect every conceivable technological accumulation from the time the original model was introduced to the present. Enjoy the enhanced presence, dynamics, and beautifully organic and musical textures of the new SE models.
It is no exaggeration to say that the clock circuitry is the biggest key to high sound quality in digital music reproduction. For its flagship master clock generator Grandioso G1X, Esoteric has perfected its own in-house manufactured OCXO clock module, the Master Sound Discrete Clock. The G1X’s unique discrete circuitry has been highly acclaimed for its superior musical expressiveness, creating a buzz in the world of high-end audio that has traditionally been described only in terms of technical specifications.
The “Master Sound Discrete Clock for Digital Player” used in the new SE model applies the basic design concept of G1X’s in-house manufactured OCXO module to the internal clock of the digital player models. The unique circuit design using carefully selected discrete components, such as a large crystal oscillator, achieves high sound quality that reflects Esoteric’s philosophy in every detail, which cannot be achieved with an off-the-shelf clock module. The new SE model can also be connected to the Esoteric G series external master clock generator to improve sound quality by synchronizing the internal SE clock circuitry to an even more accurate 10 MHz clock.
