The Esoteric 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’ favourite construction features, such as the VOSP Super Audio CD transport mechanism and high-rigidity aluminium 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 K-07Xs Information:
- Following in the Footsteps of the Grandioso K1: The New Dual Mono D/A Converter
- 34-bit D/A Processing for Outstanding Powers of Music
- Esoteric-HCLD: A Unique Output Buffer Circuit that Optimizes Current Transmission Expression
- ES-Link Analog: A High Sound Quality Current Transmission Analog Interface
- Generously Rated High-Speed Power Supply
- USB Audio Interface with DSD 22.5MHz and PCM 768kHz/32-Bit Asynchronous Transmission
Wide Range of Upsampling Options
In addition to playing back a digital audio source at the original sample rate, the K-07Xs can upsample PCM signals to 2x, 4x, 8x and 16x (maximum 768kHz). It can also convert a PCM source to DSD 512 (22.5MHz). A DSD filter may be switched in according to preference.
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.
The analog audio output can be switched between ES-LINK Analog, RCA, and XLR. Hot 2 or Hot 3 XLR pin assignments can also be selected. Loss in audio quality is eliminated with a non-contact system by performing phase inversion in the digital domain.
