Can also be used after the IV circuit, e.g.

> Are those buffers intended for Single Ended DAC chips?

Each PCB is meant for 2 channels of single ended, or one channel of balanced.
So you would need 2 boards for stereo balanced.

Thanks, Patrick.
Just to be clear, is the Joachim Gerhard Filter Buffer an evolvement if the Sen/Sen I/V?
Can the Joachim Gerhard Filter Buffer be operated on batteries, or conventional PSU, or both?
Will there be an option to wire the Buffer for Current Output DAC Chips?

It evolved round my ES9022 / WM8804 modules that Joachim had.
Please read the thread linked in post #1 for details.

Both.

No.
