Now approacing 90dB if you believe the simulation with with this experimental circuit.
You'll want to find something else to do while it simulates.
How to inprove it further?

Simulation won't asolutely prove what circuits would produce low THD,
but it will pretty definitely show which circuits won't.

Of course, a sim like this needs good opamp models.

If one builds it and measures it, what would you use to measure the
distortion?
