He also explained that the theoretical optimum mix (but practically unachievable) between A and D was 0% A and 100% D; but that the changes had moved them from 2%/98% to 0.5%/99.5%, improving precision by a factor of four.

Thanks, Ian, for the detailed report.  

What does the theoretical optimum mix of the A ratio of 0:100 mean?  Does that mean that the Pro series require less Class A output than before to produce the equivalent power output (when compared to the existing series)?

I am trying to understand the concept of precision having being improved by a factor of 4 as well

My technical understanding is limited. I draw parallels with the Quad current dumping approach where the slight B imperfections were filled in by the precise A part. So I assumed the point was that the absence of need for any "D" correction was ideal in theory buy not deliverable in practice. so what was 98% D with a 2% A contribution now becomes 99.5% D and 0.5% A - so the correction has reduced by a factor of 4 meaning the precision has improved by a factor of 4. Beyond that I'm lost.
