Need help simulating discrete impedance matching buffer in LTSpice - using 2N7002 and BC856

Woah nice good price.
Be fun to hear that dual package that TI released too.
As far as PCB design, good to leave additional compensation
filters there if stability comes a issue in real life.
Just leaves the option of having them there if needed or can be left out.

I have been doing layout for the balanced inputs using previously discussed voltage follower schematics.
Basically was making two exact copies for each side of swing.
But then upon thinking more on it, I think there should be a better way.
Fully differential discrete voltage follower.

I have put together schematics in TINA TI, but I am still in lack of experience to make it work. just relates the concept
As always, attahced

Maybe I should do something like this for LTP?

Should probably take signal opposite outputs

Complimentary feedback quad for balanced signals.
Less parts, same result.
Just what I needed for my balanced input LM3886 boards.
By adjusting resistor values it is possible to make it produce 2nd harmonics. Still pretty low distortion.
