This question has likely been address by a few other threads. But, depending on the implementaion, the JFETBOZ might not have the voltage swing to optimize the F4's output capabilities.
What is JFETBOZ? Is it

With a 35V supply? Or with the optimized for distortion 16V supply?
I'd guess you might get about +and- 15V out of the former and I suppose +and- 7V out of the latter. That would be expecting alot. To fully drive a stock F4 I believe you would want about 22V(44Vp-p).
Personally, even if I had the efficiency to typically use only a small amount of the F4's power, I would still enjoy the possible headroom 😀
