The Line Noise BlackHole occupies a fairly diminutive metal case with an IEC input and a power switch on the back panel. A single multi-compatibility outlet is on the front panel (it works for both IEC three-prong and Schuko plugs) and is accompanied by a single status LED. The Snub Station Zero’s case has slightly larger dimensions, sports the same back panel IEC input and power switch, but has a total of three multi-compatibility outlets on the front panel. Two of them are identified in the manual as “low power,” and are designed for less demanding audio equipment. The third outlet, designated as “high power” and “soft start,” provides a more effective interface with high-current devices like power amplifiers. And whether vintage, solid state, or tubes, all would benefit from reducing the burst of transformer energy that occurs when those devices are fired up. The reduction of in-rush current translates not only into reduced noise at startup, but also increased life and reduced wear on the amplifier’s transformer windings. The front panel has a pair of LEDs, one for power-on status and another that’s marked “SSR” that lights after the input power has stabilized.
