Yes they are quirky, and more likely to break-into-song than other parts, but they can have fantastic performance sonically, imo. A "kink" in the Bode plot -- well it wouldn't be the first time...

I just found the part lacking in any depth or low level detail, to my ears it's a dry filter of the dynamics. I just don't care for most of AD's opamps.

We'll have to agree to disagree here.
I'm thinking of a well regarded digital audio product that has nothing but AD parts. Renowned, as it turns out, for its superior low-level performance.
Even with the dreaded 797! How can it be?
In your experience, is there any parameter we can look to for better "low level detail" or "dynamic filtering?"
I know what pleases the ear is all that _really_ matters, but sometimes measurements can also be useful, imo.
