Based on my experience with LH Labs Indiegogo campaign, its been almost two years for their top of the line DACs to come out, recommend to look at their thread and you will get an idea how frustrated people get, including myself. Looks like the process of developing something from the get go is not clear cut and timelines shift all the time. I think Centrance have been very open in explaining all the issues. Do you think he is frustrated I am sure he is. As far as refund it won't hurt to ask but based on Indiegogo rules, it is up to the company to refund if they want after campaign is funded. In my LH Labs case, the answer was a big NO. But they offered a credit for any other product. Believe me I feel your pain, but I will start complaining in Jan. As of now I will give them a few more months.
