No, I think it's Class B or Class A/B SS amps that have that problem but I don't think the problem extends all the way to 1 watt.
Is the N-Core amp Class A?

no, class d....
try it! you know you want to!
So, if you know, is there the equivalent of crossover distortion in a Class D amplifier?
I just read the IR pdf about Class D amplifiers and there seems to be, having to do with switching and dead time.
The chart I'm looking at shows that the HD starts higher and doesn't drop to minimum until 10 watts output.
After reading that pdf it seems that Class D amplifiers are held together with a wing and a prayer.
I would really like to hear one of these things.
Like CD, once you understand how PCM works it's amazing that they sound as good as they do.

"Note: THD+N includes noise.
Noise (mainly thermal noise from resistors) dominates below 10W. Since the noise level is constant and absolute its amplitude relative to the test signal level, expressed in percents, is higher for lower signal levels. This in no way implies that distortion performance has an optimum at 10W but that at lower powers it is completely unmeasurable amongst the (very low) noise. This is why distortion spectra are only shown for high power levels where any distortion of note exists. "First Watt" performance is, in fact, first rate. "

I was reading the International Rectifier pdf.
The above is from the N-Core pdf that you linked and no, I don't see the note.
I searched the pdf for "Note: THD+N includes noise" and came up blank.
The above is not THD+N to start with.
BTW not that it matters but it looks like this one bottoms out at 6 watts vs. the 10 watts from the IR pdf.

I was looking at the nc1200 datasheet that you linked in this post,

The only thing that matters is how it sounds. Bring of over and we'll listen to it!

...is how it sounds.
Yep.
I guess you have now backed down from your objective claims.
