Esoteric Grandioso D1 Mono DACs Voltage: 240V. Excellent condition trade-in item. No boxes or owners manual but comes with standard power cable. Buyer pays shipping.
A monaural configuration for the ultimate evolutionary step toward the ideal stereo The D1 follows the monaural configuration of the D-01, which Esoteric introduced in 2004 as the world's first monaural D/A converter. The D-01 was developed with the goal of attaining the highest level of channel separation and the ideal power supply to each channel. In the new D1, Esoteric have introduced the latest technology and further enhanced the design. The right and left channels can now be link-connected with a single HDMI cable (provided), and easy input from external source devices is possible. With the D1, you can enjoy a world of incredible stereo with the rich stereo image and sonic depth that is only possible with a monaural configuration.
Outstanding sound quality with 36-bit processing resolution
Aiming for the pinnacle of sound quality, Esoteric have incorporated the AK4495S, a state-of-the-art 32-bit DAC device developed by Asahi Kasei Microdevices Corporation. Sixteen circuits per channel are provided to achieve phenomenal linearity and low noise. In addition to direct processing of the DSD signal, a new 36-bit D/A processing algorithm has been adopted for analog conversion of the PCM signal at 36-bit resolution. The result is fine, smooth sound quality as along with high resolution.
ESOTERIC-HCLD*: ESOTERIC's own output buffer circuit featuring fortified current transmission
A high-speed current transmission capability is the most important factor of an analog output circuit for transmitting a wide dynamic range of music signals downstream without deficiencies. For the ultimate performance as a line driver, the output buffer amplifier circuit of the D1 makes extensive use of materials and is configured with its own board separate from the D/A converter. The current output capability is high, and the high-performance elements adopted for the slew rate, which indicates response speed, boast the incredibly high speed of 2000V/㎲. The ability to supply instant current is maximized with an extravagant buffer circuit configuration utilizing one circuit for RCA output and one circuit each for hot and cold connections for XLR output. With the ESOTERIC-HCLD, the D1 reproduces the dynamism of music with breathtaking reality.
