Predominant 2nd order means that there is an unbalance. All push-pull derivates reduce 2nd order if made correctly, (well balanced). It would be interesting to know which level your spectrum shots are taken at, dependng on how close to clipping distortion levels will vary very much, even more so for higher order. In order to make fair comparison I always define output power at clipping as the power level at 1% THD, I also compare distortion levels at 1dB below clipping. What is your criteria?
