I think making CCS and rail splitter PCBs is very meaningful, because it's not just can be used for PPA, but other project as well.HA3-5002 is not very common, i suggest to make a converter for BUF634 to be used in PPA board.Next, diamond buffer, i think sijosae is more experienced in this, i will ask for his advice.
