K-07: SACD/CD Player with VOSP Mechanism and 32-Bit Dual Mono D/A
Four digital filters
USB asnychronous driver
ESOTERIC K-07 is a new model of our highly acclaimed K series Super Audio
CD/CD player. The design concept of the K-07 is clear and simple: a 2-channel
D/A converter with a disc transport that gives a stress-free musical experience,
without adding or removing anything from the original source material. Design
and engineering was completed applying all of ESOTERIC’s audio technology, and
evolutionary materials for which cost was not a consideration.
The K-07 is a high performance model that follows the philosophy of the
top-end all-in-one K-01 digital source, committed to advancing the “state of the
art” for the 2 channel audio purist, for both high resolution audio files and
VOSP (Vertically-aligned Optical Stability Platform) SACD/CD transport
mechanism with shaft-mounted pickup assembly ensures precise data leading by
keeping the optical laser axis always positioned at the center of the data
32-bit dual mono D/A converter, x 2 DAC circuit per channel (AK4392
chipset) in parallel / differential configuration
Fully balanced, high quality buffer amplifier circuits, switchable to
parallel buffered unbalanced output.
Substantial power supply, using large toroidal-core transformer, multiple
capacitors and high speed Schottky diode.
High resolution 24 bit / 192 kHz PCM digital inputs (Coax x 1, Optical x
1, USB x 1).
24 bit / 192 kHz high speed, asynchronous USB connection with PC or Mac.
D/D convert function (“RDOT” x 2 / x 4 PCM up-sampling algorithm,
Digital filter OFF mode, x 4 digital filter options include 2 types of
”short delay“ (“apodizing”) filters.
High precision VCXO (Voltage Controlled Crystal Oscillator) clock
Clock sync function supports 10MHz input, and “Direct Master Clock Link”
with corresponding master clock generators.
ESOTERIC G series external master clock generator is a system upgrade
option for more precise signal re-clocking. External clock can also be used to
re-clock PC data stream input to the K-07 via asynchronous USB connection.
32 bit accuracy output volume control / XLR output gain control (0dB/+6dB)
/ XLR pin assign convert (2-pin hot / 3-pin hot)
