Default a couple amps. critics / suggestions needed

I put this together to just show myself what works and what doesn't. There is no working prototype of those amps but I would like to hear from everyone.

The design goal is to make as simple of a design as possible. so I used an op-amp as input stage, and CF voltage amplification stage to expand the output range of the op amp. I have not calculated all the values and there is no protection circuitry nor decoupling circuitry for the op-amp so keep that in your mind.

I need suggestions / ideals on the two "different" ways the CF stage is coupled with the op-amp.

thanks in advance.

here goes the first one.

it is unlike the traditional cf vas where the op-amp output is fed to the base of the transistors. Instead, it goes onto the emitters.
