I'm on the lookout for an isolator that will work between a Raspberry Pi 3B+ running Ropieee set to "Raspberry Pi DAC (I2S)", so 24/192 max, and this very silly R-2R DAC HAT I've got.

I'm interested in anything else that might work, but I don't think the Allo Isolator can provide power up the DAC board. Happy to be corrected.
