"As a power amplifier, the OPA567 runs very well with 2 Amps at almost rail-to-rail.
I have blown-up a few of these OPA567's because of the maximum high voltage ~7.5 Volts, and some "below average" feedback power supplies.
For example, if the OPA567 is running at 2 amps, and then suddenly down to ~zero amps, the power supply and the power runs usually have enough inductance to cause a 'spike' in the output voltage from the change in the current.
I solved this problem with some big zener diodes rated at 5.6V on the +V.
Another problem was that I was driving a transformer also susceptible to causing spikes. This would force the output to have its voltage range beyond the power supplies. I solved this problem by using diodes connected to the output to ground and from the output to +V.
It would be nice if the opa567 were re-designed with these diodes in the same package."

"I used this OPA567 on a university project, it works amazing, stable with temperature and so litle distortion and I guess that distortion came from another part of my circuit anyway works pretty good."
