One each AD1862 & AD1865 both with brand new N-J grade chips.
Both boards have header pins inserted for separate supply to op-amps. I recommend using dupont 2.54mm single pin female prototyping leads.
The DACs will need an I2S input module, either Amanero type or XMOS. It is worth trying the new York Pico by Eclipse as discussed in the vendors forum, this looks a very good design. For sale now on Tindie.

Hi there. I have a couple of AD1865 chips and I'd like to use one on your kit. I'm new to the DIY digital source world (but have DIY tube amp experience) and I have a few basic questions.
Do I need a further gain stage before connecting to an active preamp? Or is the tube I/V stage sufficient?
Which power supply do you recommend?
