Negative differential resistance would be the better term, since it has to have some resistance in order to produce negative resistance change. Fluorescent tubes are also a negative resistance devices.
I cannot see how this device would help with gear that already has built in voltage regulators - pretty much any device other than power amps, but today many power amps have SMPS including half of class D amps and some class AB amps like the newest high power amps from Rowland. Perhaps resistance of this device have some filtering effect reducing power line noise.
