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 optimizes 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.
