Not even close. The APX555 or 555B has another 15-20dB to play with. Ask @amirm

But, that's only at a measly 5W. One data point at 1kHz 5W is just that, one data point.
I didn’t realize that the AP555 was good for 150dB dynamic range. I agree we need to see a full set of power vs distortion sweeps at different frequencies into 8/4/2 Ohm loads. Along with multitone and IMD plots.

OPA1656 as per the man himself.
I just noticed the following update on the product page: "One Texas Instrument OPA1656IDR OPA per channel is used."
