Dachang licensed K03XD, a new product launched in 2019. On the basis of K03XS, technology derived from flagship G1 and superior machine K01X is introduced, and the bald head is updated, and the sound performance is better than the previous generation K03XS. K03SX has been discontinued and out of stock.
Although K-03Xs is one order lower than K-01Xs, the internal design is still breathtaking. The most important optical disc reading mechanism uses VRDS-NEO [VMK-3.5-10], which weighs up to 11.2kg including the base, the thickness of the holder is up to 1 cm, and the spindle motor equipped with high magnetic flux density magnets can keep CD/SACD The stable rotation speed allows the laser read head to read the digital audio from the disc more accurately.
In terms of DAC circuit, K-03Xs inherits the design of Esoteric’s flagship CD/SACD player Grandioso K1. It uses two Asahi Kasei AKM AK4497 32-bit DAC chips and MUSES 8820 OP chips, and supports 34-bit character depth processing. Ability to help restore the digital signal to the original analog signal. With the VCXO clock generation circuit, it can reduce the jitter of the digital audio and accurately reproduce the music signal.
The analog circuit part adopts the "HCLD high current level drive" technology developed exclusively by Esoteric, and its conversion rate can be as high as 2,000V/μs, is conducive to faithfully restore the ever-changing moment details in the audio. In addition to the general RCA unbalanced and XLR balanced analog output terminals, it also provides an "ES-LINK Analog" terminal specifically connected to the Esoteric amplifier, retaining the high current output characteristics of K-03Xs.
In addition to CD/SACD turntables, K-03Xs also has an indispensable USB input terminal. With the original HR Audio Player software developed by the manufacturer, the DSD audio sampling rate can support up to 22.5MHz, and the PCM can support up to 768kHz/32bit. With the Bulk Pet transmission function of the software, it can adjust the stability of the digital audio transmission, so that the sound quality can be further improved.
