Spot Japan ESOTERIC K-07X CD/SACD machine brand new licensed genuine warranty
Following the K-01Xs, K-03Xs and K-05Xs, Esoteric’s entry-level SACD/CD turntables also launched a new generation of K-07Xs, which completely condensed the flagship Grandioso K1 technology, such as the VOSP SACD disc structure and high-rigidity aluminum alloy. The chassis, the proud latest digital-to-analog conversion architecture, the latest digital circuit, and the powerful output amplifier and power supply, the excellent physique is expected.
K-07Xs adopts the same VOSP laser reading mechanism as the Grandioso high-end model, and is covered with a 8mm thick steel large-diameter stabilizer, which can improve the rigidity of the mechanical structure, avoid the vibration of the disc during high-speed rotation, and keep the optical axis Extremely vertical angle to achieve high-precision signal reading. Based on the latest architecture of Grandioso K1, K-07Xs redesigned a dual mono digital-to-analog converter. Each channel uses 4 sets of Asahi Kasei AK4493 DAC chips to form a parallel/differential circuit to minimize distortion. Coupled with the unique 34bit D/A conversion, the resolution is 1,024 times that of 32bit, which can effectively take advantage of the high-bit data, keep the calculation error to a minimum, and faithfully convert it into an analog signal. And like K-01Xs and K-03Xs, K-07Xs directly add a buffer amplifier after the digital-to-analog conversion output, so whether it is low-frequency power or small-level music signals, it can have better playback performance.
In the output part, the output buffer circuit of K-07Xs has been updated and adopts HCLD like high-end models.(High Current Line Driver)High current linear driver, slew rate up to 2,000V/μs, and each channel is equipped with 2 sets of HCLD, the XLR balanced output is differentially amplified, and the RCA unbalanced output is driven in parallel, which has better dynamic performance. In addition, K-07Xs is also equipped with ES-LINK Analog interface, which can effectively exert the performance of the HCLD buffer circuit, so that the signal is not easily affected by impedance in the transmission path. With its own amplifier, it can best play the advantages of ES-LINK.
K-07Xs has an upscaling function, which can upscaling PCM by 2/4/8/16 times(Up to 768kHz), Or convert PCM to DSD 22.5MHz and then perform digital-to-analog conversion. K-07Xs also provides DAC function, coaxial and optical input supports up to 192kHz/24bit PCM and 2.8MHz DSD(DoP), Asynchronous USB transmission can support up to 22.5MHz DSD and 768kHz/32bit PCM. In addition, the K-07Xs has a built-in high-precision VCXO clock, and it can also be connected to an external high-precision master frequency generator such as G-02X to synchronize the K-07X with external frequency signals to further improve the sound quality.
