The K-07Xs captures the essence of the Grandioso K1, with revolutionary innovations throughout the design. The Xs lets nothing get in the way of the music, providing an emotionally involving playback experience. The third generation of the K Series Super Audio CD Player, the K-07Xs condenses all of the best technology from the Grandioso K1. It has all of the users' favorite construction features, such as the VOSP Super Audio CD transport mechanism and high-rigidity aluminum chassis, along with a range of new ones such as the latest digital circuitry, a D/A converter based on the latest K1 platform, high current output buffer amplifiers and a high-stability, low-noise power supply.
Esoteric's unique VOSP* mechanism employs the same pick-up assembly used in our Grandioso line of high-end SACD players. As the pickup moves, the laser beam maintains a precise perpendicular optical axis orientation relative to the disc surface, ensuring highly accurate data reading. The mechanism is held by a robust steel plate and an 8mm-thick large steel stabilizer for superior anti-resonance properties.
The digital-analog converter section has been fully redesigned based on the latest platform used in the Grandioso K1. An AK4493 32-bit DAC from Asahi Kasei Electronics has been combined with premium components and the latest design technology to provide an exceptional level of sound quality. Four converters are used in each channel in a parallel differential configuration, to provide class-leading linearity and extremely low distortion. Like the K-01Xs and K-03Xs, additional buffer amplifiers are placed immediately after the DAC outputs and this gives a more powerful bass and better reproduction of low-level signals. The layout of the DAC power section has been revised to provide further improvements to the noise performance and stability.
Three digital inputs (USB, coaxial, and optical) enable connection to a wide range of systems. Coaxial and optical inputs support DSD 2.8 MHz (DoP) input and PCM of up to 192 kHz/24-bit.
The heart of any digital player is the clock circuit, and the K-07Xs's has been designed for quality with a high-accuracy VCXO (voltage-controlled crystal oscillator). It can also be connected to a high-precision master clock generator such as the G-02X for even higher sound quality.
