"Did you check THD at MAX power output?"
Yes, but the question puts the cart before the horse. When making the measurement, it has to be decided first what level of distortion will be used in determining that maximum output has been reached. I use 1%, because A) that's the level at which most people can first begin to identify the effect as actual distortion, and B) the amplifier should only ever reach this level on brief, intermittent musical peaks. Here are the final specs for distortion:
5W output: < 0.035% THD, < 0.1% IMD
30W output: < 1% THD, < 1% IMD
