-12dB less THD@100KHz than normal TMC.

My question is, how many poles in there?

The slew rate looks like it is around 20V/µs.
The phase margin is almost 90°.
Could the 330pF be reduced slightly, to give some performance benefit?

There is only 1/3 of the output voltage between each 330pF. The slew rate is about the same if you remove all the resistors around the capacitors. In my case, if you remove all the resistor, the equivalent miller cap is about 100pF.
