Then what's the question?

You would have to have access to a good distortion meter too find out how 
good it is and to try to improve it.  I measured what I could and gave the 
results.  You are more than welcome to take this farther, of course.

For me, the distortion is low enough, but for highly precise work it may 
not be, depending on the application.

Sorry -- the point of all this is...?
