ESOTERIC D-07X

This state-of-the-art D/A converter provides uncompromising quality with PC audio playback using a USB connection, S/PDIF Coaxial, AES/EBU or TosLink Optical as well as when connected to an ESOTERIC Super Audio CD/CD transport. Audio performance has been improved using a dual/mono configuration in which multiple 32 bit D/A conversion circuits are combined in parallel, as well as by utilizing a parallel buffer amplifier for unbalanced analog outputs. This model uses cutting edge technology, including 192kHz/24bit USB input compatible with asynchronous transfer, high accuracy clock circuit, multiple D/D conversion options.

 

The D/A converter IC’ s of the D-07X incorporate 32-bit “AK4392” chipsets, manufactured by ASAHI KASEI Microdevices Corporation. Two circuits per channel in parallel/differential output configurations are provided to achieve phenomenal linearity and low noise. The converters and analog output circuits, which make up a fully dual mono configuration, are located on the left and right hand sides of the board, completely separated from the digital signal processing circuit. This layout allows an excellent channel separation and high-quality playback with rich localization and sonic depth.

 

For the final stage of analog audio output (buffer amplifier), New JRC’ s high end audio operational amplifier MUSES is used. These buffer circuits are laid out symmetrically for each of the hot/cold signal lines to construct a fully balanced configuration. When the RCA audio output is selected, the buffer amplifier is switched to parallel configuration. These enhancements provide the best sound quality for each of the balanced and unbalanced audio signal outputs.

 

A high quality power supply is essential to high end audio equipments. The power supply circuit of the D-07X is substantially built with extra large, low loss, low magnetic flux leakage R-core transformer, multiple large capacitors and high speed Schottky diode. This circuit supplies low-impedance, clean, stable power to all circuits very quickly to achieve ultimate level of detail expression.

 

The D-07X features multiple digital inputs (USB, XLR, optical ×1, coax ×2), and all these inputs support high-sampling-rate sources up to 24 bit / 192kHz. The D-07X supports ES-LINK (XLR) connection with ESOTERIC SACD transport for SACD playback.

 

The USB input supports asynchronous transmission up to 24 bit / 192kHz using ESOTERIC’ s original driver software for PC or MAC. Additionally, a USB isolator allows high quality reproduction of studio master sources by blocking the noise from computer.

 

In addition to playback at the original sample rate and word length, extensive D/D conversion modes for PCM formats include PCM up conversion to x 2 or x 4 from the original sampling frequency, using the “RDOT” algorithm, as well as PCM > DSD conversion to convert the PCM audio signal to DSD format similar to Super Audio CD. Super Audio CD is directly converted into analog signals and played back.
