Default Op-amps in IV, filter and buffer stages of a DAC

Maybe someone should start an OP_AMP section to diyaudio.

I am currently using a theta dac with OPA627 in IV and filter positions and BUF634 in buffer position.
These replaced AD844, AD741 and LM6321 respectively.

Anyone tried AD8610, AD8065, AD825 and AD843 in any of these positions?

Alos, my pre-amp is based on Pavel Macura's and uses OPA-627 with a BUF634. Any op-amp rolling done here?
