Alrau1, thanks for adding details about mode of operation of the LC-1800. What I like about it (and many similar units) is the noise rejection by means of a toroidal transformer. It works wonders for digital!
You'll also notice that I specifically said to NOT connect a power amplifier through this gadget. It does limit current which is an issue with high power units.
I guess I don't encounter large voltage fluctuations, so I haven't noticed erratic behavior. Like I said, there are other units and i'm sure that some of these do not switch taps but just filter the noise through a magnetic circuit. These are much more effective than some pathetic implementations with lots of LEDs and a digital display on the front panel...
