This update has required significant optimization of code for the main FPGA of R2R ladder DAC which has improved sound quality.
The new hybrid USB XMOS xCore 200 (dual core) + FPGA circuitry enables the high-resolution file playback up to 768kHz PCM and up to DSD256 (Quad DSD)
Upgrading to xHD
The update for the Formula units of existing owners consists of the following hardware / firmware modifications:
1. new hybrid USB Board cod. A108 (high-resolution up to 768kHz PCM and DSD256 (Quad DSD)
2. hardware modification of board P1108 connected to USB board
3. new firmware of main FPGA (R2R ladder DAC) with optimization of the code
4. update of firmware of main microcontroller STM32
