Grandioso PS1

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, and further enhances 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 closer level of performance as 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 power supply that optimises the performance of the 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.

The benefits of connecting the PS1 to the K1X extend beyond a mere increase in the scale of the analogue circuit (D/A converter module) power supply from two transformers to four. By shutting down the K1X’s two analogue circuit power transformers, the influence of transformer vibration and magnetic flux leakage on the analogue circuits is also greatly reduced, thus enabling further improvements to overall sound quality.
