@mewsickbuff, there seems to be a possibility of misunderstanding since our last email exchange in early April.
To ensure clear understanding, we would like to clarify that the FPGA firmware update is provided free of charge for all DENAFRIPS DAC owners.
FAQ: I bought the DAC used and/or from the grey market. Will I be entitled for the Firmware Update?
Ans: We understand some of you may have purchased the DAC used and/or from the grey market (sadly). Vinshine Audio is willing to extend our goodwill support to you. We are good people afterall. Please enter 'Used' or 'Grey' in the Order Number.

Many thanks.
