I understand where you are coming from. While I am happy that TPA has made Sabre chip DACs readily available for DIYers, I prefer the process that AMB and others follow, which is incorporating the input of others and open prototyping during the development process. It definitely seems to cut down on the subsequent "tweaks" and "upgrades."
For example, I found it difficult to keep track of the optimal parts values for the original IVY (C1-C4 going from 10nF to jumpered; C13-C16 going from 10nF to 1nF; R1-R4 values changing...). It was especially annoying to buy the IVY kit and then having to remove and replace parts with ones that were not included with the kit
I kept thinking, "Shouldn't this have already been figured out?" If not, perhaps they should just be selling PCBs, and then we'd expect that some parts values may change. To me, a kit implies a finished
