👍 Dual AK4499EX & AK4191 DAC Chips ▶️ The GUSTARD A26 DAC combines two AK4499EX DAC chips with one AK4191 modulator from Asahi Kasei Microdevices. With impartial energy provide and grounding for every channel, separate digital-analog structure eliminates interferences from the start.
👍 FPGA Exclusive Technology & Streamer / Renderer ▶️ Adopting FPGA unique expertise, the A26 options sign routing, clock administration, 2rd order PLL, DOP decoding, and Depop for PCM & DSD. Besides, using Streamer/Renderer, an quick access to high-quality on-line streams, the GUSTARD A26 can helps Roon /UPnP /HQ Player NAA at current, and there will likely be extra protocols sooner or later.
👍 Clock Synthetization & XMOS XU216 Solution ▶️ Equipped with K2, ultra-low noise clock synthesizer, the A26 DAC contains a precision clock from native oscillators or exterior clock in. It is value mentioning that the GUSTARD A26 can change the enter sign’ s clock with precision oscillators (native or exterior) and keep away from the interference from the enter supply’ s clock. In addition, the A26 DAC applies XU216 from XMOS, supporting as much as PCM768 (with MQA-support) and DSD512.
👍 LPF Discrete Circuits Design ▶️ LPF is particularly designed for the AK4499EX utilizing discrete gadgets, whose ultimate parameters of the circuit are adjusted with subjective listening. Different from ICs, these discrete circuits present the chances to regulate each element in sound and efficiency. However, these parasitic results would introduce large challenges to improvement expertise and system’s high quality.
👍 Full-Functional Remote Control ▶️ Except for its glorious configuration, GUSTARD A26 characterizes a sandblasted aluminum alloy case with an OLED show and a contact panel. And customers can simply take pleasure in their music wealthy in particulars through the use of the usual distant management.
