What is meant by "clean" is the perfect sine wave, which is what Class A is all about,albeit very inefficient, and that's where quality beats quantity.
As soon as power is turned up from Class A to Class AB etc.., the switching output transistors introduce a small spike in the sine wave each time they turn on/off, called "Notch Distortion" or Transient InterModulation Distortion a.k.a (T.I.M), which is by far more detrimental to sound quality, and preventing damage to the speakers.
Now the term "dirty power" umm.. well, according to the specifications that came with my alarm clock radio it sounds very clean, despite the fact that distortion figures are higher than my car stereo.
Some people view the "sonic signature" of some brands which may or may not "sonically match" the sonic signature of other components connected to it as dirty or poor, which is in my opinion a misguided statement. Many of us have had customers that recently purchased a system, only to be dissatistfied with it's sonic quality, and in many cases it's due to a compromise on one product or another.
Sooo, Poor performance of a system in my opinion is mainly due to either mismatched equipment or an improper install.

I wash my power with Irrish Spring.

I think when we talk about dirty power, what is meant is amplifiers that are not transparent and end up "adding" junk to the signal. That being said, most stuff out there is dirty then............. that means you're all a bunch of dirty bastards running dirty power.............. I feel dirty now just being part of this dirty thread. Then again.............. shudda up Dukk, I KNOW what you're gonna say you old bag of dirt
