Gustard X30

Approximately 2 weeks delivery time from order.

With its X30, Gustard presents a DAC with exceptional performance and versatility. This DAC is equipped with four ES9039SPRO DAC chips combined with an ES9311Q linear regulator and a second-generation XU216 USB XMOS interface. This enables it to support high-resolution sampling rates up to PCM 32bit 768kHz, DSD512 and MQA. It also has a preamplifier stage with R2R volume control and an Ethernet LAN port via an RJ45 connector, which allows it to function as a network player. There is also an FPGA with OCXO crystal oscillators and a connector for an external 10MHz clock. The many digital and optical inputs include USB, Toslink optical, SPDIF coaxial, I2S via HDMI and a micro SD slot. Two 3.5mm jack triggers complete the package, and the outputs are via stereo RCA or balanced stereo XLR. The design and ergonomics feature an attractive front display and elegant curves, as well as a remote control for easy operation from a distance, making the X30 an excellent choice as an audio gateway and a central element of your Hi-Fi system.

GUSTARD X30: XMOS XU216 USB interface and 4x DAC ES9039SPRO + ES9311Q
Gustard X30 benefits from four ES9039SPRO DAC chips combined with an ES9311Q linear regulator and an XU216 USB XMOS interface. This chipset enables it to support high-resolution streams up to PCM 32bit 768kHz, DSD512 and MQA. The ES9311Q ultra-low noise linear regulator optimizes the four DAC chips, achieving a dynamic range of over 130dB and a signal-to-noise ratio of over 129dB. An analog class A low-pass filter circuit based on discrete components provides flexibility in adjusting each parameter of the DAC chips, maximizing their performance.

GUSTARD X30: digital filter
An autonomous DSP SHARC digital filter reduces noise using a 64-bit floating point algorithm and noise shaping techniques. The X30 also features four DSD filters, three PCM filters, and support for NOS mode.

GUSTARD X30: passive analog preamplifier
The preamplifier stage features R2R volume control for adjustment without loss of signal quality, as well as the option of direct connection to a power amplifier or active speakers. A fixed output level is also available if you wish to connect the X30 to an external preamplifier.

GUSTARD X30: network player function
An Ethernet LAN RJ45 port allows the X30 to connect to the network and supports Roon, Airplay, DLNA, UPnP or NAA (Network Audio Adapter). Streaming platforms are thus available, in particular via an interface developed with Celaudio. This interface is specifically designed to optimize audio reproduction with devices that combine hardware and software.

GUSTARD X30: a high-end clock system
The X30's clock system is equipped with thermostatically controlled OCXO crystal oscillators and a K2 synthesizer. This technology allows the DAC to use either its internal OCXO clock or an external 10MHz clock. The device is accompanied by an FGPA chip for excellent stability.

GUSTARD X30: balanced power supply
The X30 benefits from two toroidal transformers that power the analog and digital parts of the device independently to avoid interference. In addition, the power supply for the two DAC channels is separate, with independent voltage stabilizers.
