I finally got around to take some measurements on the 8600S using my scope and sound card.

With an 8 ohm load, I measured 0.98% THD (mostly 2nd order harmonic) at 1W output, and 2.3% THD (2nd and 3d harmonic) at 5W output.

Onset of clipping starts at 5.8W output (20Vp-p). It is quite soft and starts clipping at the bottom of the signal (asymmetrical). The peak output continues to increase to 23.2Vp-p (9.2Vrms), which works out to over 10.5W.
