I reported above that the input stage of my LAiV Harmony Dac died. After I reported the problem, I had a response in a matter of hours that a new board would be sent to me. It arrived by FedEx along with a ground strap, white gloves, new screws and a new warranty sticker in about three days. Half an hour to install following a YouTube video with installation instructions and the problem was solved.
LAiV wanted the old board back. I took it to UPS and they wanted $115.00 to send the old board back (maybe six ounces). I then went to the US post office and it cost $14.00 to send it back.
I asked why the failure and was told that a board supplier had sent an initial batch of boards with a latent defect and there hasn't been a problem since.
