Esoteric N-01XD SE Netowork DAC
The N-01XD is equipped with a Master Sound Discrete DAC, developed entirely in-house to achieve the original master sound, and a high-quality network module that delivers a three-dimensional sound as if you were listening to a vinyl recording. The N-01XD is now even more advanced as an SE model with further sound quality updates. Master Sound Discrete DACBringing Out All the Dynamics and Energy of Music. Unattainable by integrated chips, our goal was to assemble carefully selected and tested discrete components into a complete circuit that could perfectly reproduce all the dynamics and energy of music. Our top engineering teams put their pride on the line to design and produce a quality of sound that can only be found in the “Master Sound Discrete DAC” discrete D/A converter. Luxurious Materials and Powerful Current Output The N-01XD SE’s Master Sound Discrete DAC is the most revolutionary two-channel stereo DAC circuit in Esoteric’s history and is based on the original circuit developed for the Grandioso D1X SE Monoblock D/A Converter. As an extension of the D1X SE’s design philosophy, an abundance of luxurious materials has been invested in the construction of N-01XD SE’s Master Sound Discrete DAC, including 32 separate elements for each channel. Each of these 32 elements, including such key components as a clock driver, logic circuitry, capacitors and resistors, are kept independent to ensure the purest output with virtually no loss of musical energy. Advanced Digital Processing Capability The N-01XD SE incorporates Esoteric’s exclusive Delta-Sigma (ΔΣ) modulator supporting 64-bit/512Fs audio frequency sampling. To perform D/A conversion on par with the excellent DSD and PCM format characteristics, separate FPGA* digital processing algorithms have been developed for each conversion process. This enables the N-01XD SE to extract the optimum sound quality from CDs, Super Audio CDs, and network audio playback. Upgraded with IDM-01 and Other Quality Parts In the new SE model, the discrete parts of the analog circuitry on the DAC board have been refreshed for even better sound quality. The amplifier element is the original “Integrated Discrete-Amplifier Module IDM-01”. The materials, circuit patterns, and layout have been carefully studied by Esoteric’s engineers as if designing an amplifier with a discrete configuration, and the extremely short signal path that takes advantage of integrated circuits amplifies the vibrancy of music in a dynamic and subtle way. The IDM-01 and other analog parts, such as analog filter resistors and capacitors, have been carefully selected to achieve a more vivid live sound, improved audible dynamics, and a more organic texture. Unique Esoteric-HCLD* Output Buffer Circuit with Enhanced Current Transmission The N-01XD SE’s Esoteric-HCLD output buffer amplifier boasts an astonishing high-speed slew rate (response speed) of 2,000V/µs. Current transfer and speed – the most important factors in the design of any analog output circuit – have been pushed to the limit, while the array of EDLC** supercapacitors used in the buffer circuit's power supply provides a staggering 250,000μF of capacitance per channel for solid bass support and exceptionally dynamic music reproduction.*HCLD: High Current Line Driver**EDLC = Electric Double-layer Capacitor ES-Link Analog – Esoteric’s Proprietary Current Transmission In addition to line connections (XLR, RCA), ES-Link Analog, Esoteric’s proprietary current transmission system, is employed for connection to an amplifier. ES-Link Analog is the ideal method for audio signal transmission. Compared to the conventional voltage transmission, it transmits approximately 100 times more current, making it less susceptible to noise and sending the full energy of the music to the amplifier.Also, it is not affected by the impedance of the interconnects running between the source device and amplifier, so it maintains a perfect integrity between the output signal of the source and the input signal to the amplifier.
