I2S connectionWhy do you need the Chameleon if going I2S connection? You don't. Easy enough to stack those DACs on a perf board with the required caps and just go.
You would need a power supply but if you are going down this road that should not be an issue - plenty of add-on PSUs out there. Would cost far less than buying the chameleon.
Remove the main board and you no longer have a Chameleon.
- Just trying to posit a little centrist gestalt.
