The ultra-precise 32-bit FPGA DAC “Extraudio Proprietary System" reproduces analog sound full of nuances, without digital sharpness, without any errors, thanks to the quantization depth from 28 to 32 bits. The resistive ladder is adjusted through a second FPGA, which is responsible only for converting and correcting the linearity of the four DAC modules, then we have another ARM FPGA with the latest technology for sampling frequency selection, input selection and digital signal generation, freeing the main FPGA from all this work.
