Hi Fallo,

You're correct that power conditioners can help eliminate video artifacts (banding, lines that creap vertically up or down the screen and the like) because problems like those often orginate in the megahertz range (millions of Hz), which is why video is affected.

I was speaking of power conditioners' lack of benefits in the audio frequency region (20 Hz - 20 kHz). Thanks for pointing out the practical benefits as well.
