I have an inexpensive 12v 5a Zero Zone powering my NUC. No idea if it makes a difference as I already had it and not being used so figured why not. Running steady a couple of years now. What has made a huge difference lately was the addition of a couple of AQ AC iPurifiers to the server closet. It’s very busy sharing it with all the network gear and computer gear in the office. So best getting the Nucleus away from the hifi circuits, and cleaning up the power (plus the AQ offers surge protection).
Im not an AQ salesperson! but I do have a third one coming today for the opticalRendu line. It’s a dedicated circuit so I don’t expect too much improvement but at the very least it will offer some surge protection (had a power supply fry from a downed line last year). IMO probably the best $99 you can spend in hifi today.
