Its good that you asked. It does not take golden ears to tell the difference between even order and odd order HD or the absence of them . I believe every one can do it with a little experience and training. You just have learn their effect on the sound. I actually try to predict the HD levels of speakers before testing them and I'm right most of the times. Except for high-end drivers with very low HD. For those I have no clue!
I think some people enjoy certain types of HD in their systems. I think it is a matter of personal preference and the type of music one listens to.
A while back, I actually did some experiments where I added different levels of odd order and even order HD to a song using Matlab to see their effect. They actually confirmed my previous perception of the effect of HD. I can send you the music files if I find them.
I also noticed on your website that you live close by. I should drop by to give a listen to your speakers!
You should come over for VI diyFEST this summer.
An aside to the distortion thing is that the amp + speaker can have less measured distortion than either separtely. One of our (dutch?) members has shown this.

I was always searching for such an event in Vancouver area but never found one! I would love to attend!
I also think it is possible for the amp + speaker combination to have a lower HD than each one alone. Since HD is a result of non-linearity in the transfer function of systems, I think it is possible that the non-linearities in the transfer functions of a certain amp and a certain speaker to cancel out to give a more linear transfer function for the whole system.
I was actually thinking on a DSP system just for the purpose of non-linearity compensation, then I searched the internet and found out I'm not the first person to think of it...damn!
