It is interesting that the second-harmonic in the 1kHz distortion measurement is higher than the third-harmonic. Seems to fit what Tyll said in his post a few pages back. Quoting him:
"For example, if the distortion is even-order, it will be much less disturbing than if it is odd-order."
Has anyone who has a PM-1 tried it with tube amplification?
