Okay, but my point was--why not just buy a better DAC that already has galvanic isolation, and skip the DDC altogether? Seems like that would make more sense than buying two separate (expensive) devices.
For instance, you could buy a Venus DAC and a Gaia DDC, and you'd pay more than you would for a Terminator II, but you'd still have arguably inferior hardware.
Or, you could buy an even lower-tier, Pontus DAC along with a Gaia DDC for less cost than a Terminator II, but again, I'd argue this is not a cost-effective solution unless you really must have a Denafrips DAC.
For instance, why not just buy a Holo Audio Spring DAC which is R2R, measures phenomenally well, and already has galvanic isolation built-in? Or pay half that price and buy a Singxer SDA-6 if delta-sigma is an option?
Just not sure I understand the rationale of building your system around a DDC, unless you're using it specifically as a digital hub.
