Try OPA1678/79 instead.
Why not OPA1641/42? More expensive but superior performance.

There are some producers, like Joe Baressi, who change monitors for each album they work on in the hopes that the new “lens” will help create a different outcome. You may or may not like this approach but it is certainly valid.One interesting thing he mentioned is that he buys old consumer stereo-systems to use as headphone amps instead of dedicated studio headphone-systems or the ubiquitous Crown DC-60s with distro or whatever, and it got me to thinking about that as I read this thread...
One thing that was not obvious to me right away was what appears to be a bootstrap capacitor C19 from the output to the junction of the R43 and R52 resistors that provide the current path to negative supply for the Vbe spreader.
The bootstrap capacitor acts as impedance multiplier.
Thanks for confirming. You do not usually seem hesitant about having an op-amp drive relatively low impedances, so I just wanted to confirm there was not something more subtle going on.
