    The amount of undesirable harmonics present in an output audio signal expressed as a precentage. The lower the percentage the better.
    Plug in an Alpine amp, and then plug in the comparable Crossfire...you really shouldnt be able to notice a difference in sound quality at all - the levels are so low.

    Also, THD is usually taken at around 1kHz. In fact, THD is dynamic and unless there is a graphical representation of the THD function for the particular amp then the rating is for less than .01% of the audible spectrum.

    "I told her about my conversation three years ago with the political leader of Islamic Jihad in Gaza. "What's the difference between suicide, which the Koran condemns, and martyrdom?" I asked. "Suicide," he replied, "is done out of despair. But remember: most of our martyrs today were very successful in their earthly lives." In short, there was a future to live for--and they detonated it anyway."

    I don't think I have looked at the THD spec on any amp I have purchased in about 10 years(and it has been longer since I compared s/n ratios on decks

    I run JL Audio amps and love them(i have no idea what their thd spec is though).
