Its obvious that your having financial issues, but the details of the project clearly stated that developement fees were non refundable. This is a crowed funded project that was aware by most of us on the condition of johns timeline reliability. Although variables have definitely changed things for some people, ultimately johns only goal of producing the very best (fdac) design (sound quality) will still be delivered.
Just because you are now unfortunately in trouble, does not allow you to expect conditions to suit you. John is pretty reasonable and has provided what help he could. If he caved in to every cry baby he would be causing trouble for himself and also risking the viability of the entire project.
Your only options are to offer your placement in the project to others or sit back and politely try to come to some kind of solution. You cant do jack otherwise.
Also your passionate belieif in already "perfect" digital audio is not held by most here. Dont try and imprint your beleif on others just because you "think" you are right. Healthy discussions are always welcome but opinionated ******* are not.
