I'm sorry I wasn't faster on the uptake concerning the .1% figure. I didn't know where that came from, but now I understand the concern about amplifier clipping above .1%, assuming the amplifier is capable of sub-.1% distortion before clipping. The problem is that not all amplifiers can provide such low distortion, and they wouldn't be able to make power claims. For the record, the 1% figure originally was just a suggestion by CEA. There is no 1% requirement in the current Rule. You just have to disclose distortion, whatever it is at the rated power.\n\nLet's save the world from bad amplification. LOL. Disclosing distortion at rated power seems most logical.
