ESOTERIC Grandioso D1X D/A Converter

A D/A converter with two monoblock housings, with L/R in separate housings. Achieves high-speed processing equivalent to 64-bit. Equipped with "ESOTERIC Master Sound Discrete DAC", a fully discrete DAC circuit with all parts completely designed in-house, including the ΔΣ modulator. Equipped with "ESOTERIC-HCLD (High Current Line Driver)", a proprietary current-enhanced output buffer circuit. Equipped with "Grandioso CustomVCXO II", a USB audio interface that supports DSD22.5MHz, PCM768kHz/32bit, and asynchronous transmission. Equipped with "ES-LINK5", a proprietary fifth-generation digital transmission method that can transmit up to 22.5MHz DSD and 768kHz/48bit PCM digitally via HDMI connection. USB input supports 22.5MHz DSD and 768kHz/32bit asynchronous transmission. Also equipped with an MQA decoder. In addition to the usual line output (XLR, RCA), the proprietary transmission method "ES-LINK Analog" is newly adopted. The power supply is designed with a discrete power regulator and is equipped with a new power supply circuit design technology called "Low Feedback DC Power Regulator" that minimizes the amount of feedback for power supply stabilization to achieve a sound with a sense of openness. It also has two large-capacity toroidal transformers.
