2 x PCB here.
Looks like a nearly perfect tweeter driver.

Assuming the kits haven't shipped yet, I'd be interested in a pair of boards.

If it would be possible to drive 4 Ohm speakers with this amp (I guess not) I would be in for 2 kits.

with reduced power i would think yes, considering it likely has basically zero output impedance

Why not bridge the buffers, and make a bridged amp?
Or will that exceed the max voltage and current ratings for the devices?

PS. have you tested or sim'd the unit into reactive loads?

opc, I just had a chance to have a better look at the measurement graphs, I don't know if this reflects badly on me or not but ... I have one huge smile after looking them over. Look forward to bringing a pair to life.

One question I had was, why does the THD fall off a cliff at around 10kHz in the measurements at 10W when at other output powers it increases with freq.? Is it just because you're well into that un-measurable realm?

yeah like he said, the THD in particular, hes measuring the Audio precision systems own distortion, the amps distortion does not figure in the graphs
