GUSTARD X30 4x ES9039SPRO
The Gustard X30 is the company's reference delta-sigma DAC, built around four ESS ES9039SPRO chips in a fully balanced quad-mono configuration, with Gustard's proprietary ACSS current output, network streaming, and a 10MHz external clock input for master clock synchronization. The most technically specified DAC in the Gustard lineup.
Type and Technology
Reference DAC and network streamer. Four ESS ES9039SPRO DAC chips in a quad-mono fully balanced configuration, two chips per channel for maximum dynamic range and channel separation. Gustard's proprietary ACSS (Active Current Signal Source) current output alongside standard balanced XLR and unbalanced RCA for direct current-mode connection to compatible amplifiers. 10MHz BNC external master clock input for synchronization with a reference clock source. Network streaming: Roon Ready, AirPlay, UPnP, NAA, Spotify Connect. LAN input supporting 100/1000Mbps. USB, coaxial, optical, AES/EBU, and I2S digital inputs. PCM up to 32-bit/768kHz; DSD512 native. Remote control included. Dynamic range greater than 130dB. THD+N less than 0.0001%.
Sound Character
The quad-mono ES9039SPRO configuration pushes measured performance to the outer boundary of what delta-sigma conversion achieves, greater than 130dB dynamic range and under 0.0001% THD+N, with the -139dB channel crosstalk at 10kHz of a fully balanced architecture. The ACSS current output provides an alternative signal path for compatible amplifiers. A flagship technical statement in the Gustard lineup.
Build and Finish
Full-width aluminum chassis at 430 x 300 x 80mm including feet. 10kg. Remote control included. Available in black.
Best For
Audiophiles who want the maximum measured performance from Gustard's delta-sigma platform with Roon Ready streaming, external master clock capability, and ACSS current output in a single chassis.
