Introduced in 2019, the Grandioso P1X/D1X is an unparalleled Super Audio CD player featuring a four-unit chassis construction that embodies the ultimate in ESOTERIC acoustic engineering expertise. The Grandioso K1X released soon after successfully combines ESOTERIC’s two most innovative P1X/D1X technologies—its VRDS-ATLAS transport mechanism and Master Sound Discrete DAC—into a single chassis design that delivers an uncompromising response to customer requests for superior sound quality in a more compact configuration, further enhancing ESOTERIC’s sterling reputation as an industry leader.

The new PS1 is a high-performance external power supply that has been specially designed for use with the K1X Super Audio CD Player. While the K1X’s integrated design offers excellent space-saving characteristics, to obtain a closer level of performance than ESOTERIC’s top-of-the-line P1X/D1X, development was focused on providing a never-before-seen level of scalability. Then, in the process of evaluating the K1X’s development, a new idea was hatched: Develop a high-performance external power supply that could deliver even greater enhancements to the K1X’s superb sound quality. As a result, the Grandioso PS1 development project was officially launched. The project resulted in a high-performance external power supply that optimizes the performance of K1X's VRDS-ATLAS CD transport and Master Sound Discrete DAC, while providing further enhancements to its already breathtakingly realistic audio playback, thus making it feel as if one is experiencing a live performance.
