Obviously that's not quite what I was asking.

I was asking if the improvements of this current mirror over simpler ones is likely to make a positive audible difference.

For definate. Different CM designs can be alot faster, have lower noise, be cascoded to get >100mOhm impedances with improvements in negative PSRR and so on. A perfectly legitimate question to ask!.

Be very vary of people with designs based on miller Cdom (all there knowledge is about that type of design) and issues with that type of design. What is advantageous to a Doug Self type design is not neccasirily to other topology's or better capabilities have already been acheived already.

I like designer's who are Off the Wall!. :)
