this interesting thread I discover by chance.
Are there any news ?
The AD829 (dual version AD826) and the AD8610 seems to be very interesting for listening test in order to get sound character like tubes - go to

An important feature for me is the fact, that the AD826 uses only one gain stage (folded cascode). At most other op-amps there are two gain stages inside of the NFB-loop, for me a disadvantage in order for a good sonic quality.
Unfortunately I don't find a simplified schematic for the AD8610 - who can upload this?
in this case this thread is of interest:
