Digicheck runs on host’s CPU, using a negligible amount of CPU power.

IMO the multitude of little improvements on ADI-2/4 Pro SE over ADI-2 Pro makes it clearly the first choice if you want to run it as the central unit of a studio.
On the other hand, if one is on a tight budget, ADI-2 Pro does serve well too, for the same purpose.
I have both, and sound-wise we are in a quality range where it’s hard to determine any difference, if exist.
Both are simply true to the source, an important factor for a studio reference.
Else mixes done, listening through it, would not translate well to the outside world.
