"DirectStream DAC converts all incoming data including PCM to 1-bit DSD using their own code implemented in a Spartan VI FPGA. Chips need not apply."

“The choice of a FPGA over a DAC chip was easy. FPGA’s allow as much or little full width math to be used as we need. Unlike typical small DAC chips, we’re not limited by the heat needed for intensive upsampling and other processing duties. We use more power and physical area to dissipate heat without conflicting with other functions on the board, most of all the analog output.

The Xilinx Spartan 6 FPGA allows complete freedom of processing power and clock choices: our design runs the input processing at 170MHz, the oversampling at 56MHz, and the output at 5.6MHz.”
