Szekeres in op-amp feedback loop?

[paulb]

Anyone out there built a Szekeres MOSFET amp within the feedback loop of an op-amp? I was thinking of trying both this and the "stock" version (op-amp with its own feedback driving the MOSFET) and seeing if I could tell the difference.

Apologies in advance to the purists...
