Solid state -Two-stage cascode driven lateral mosfet design, so much better than vertical mosfet and bipolar transistor amps.
Tube - Parafeed or Ultra Parafeed topologies.

Hey Wiz...want to give some actual examples...
Especially how the eliminates MOSFET mist...
And just tried to have a look at your Wizard Ultimate site...
But got told to "bugger off" (note that's Aussie Slang for - you are not welcome)...

Ultimate is a paysite, for members only.

Which mosfet amps has that mist...?

That's class A with constant damping factor and only low local feedback or nothing in the cascode driver stage.

Mosfet mist is from running them too low on operating Bias , early MOSFET designers did this, Mosfet mist hasn't been an issue for at least 20 yrs TMK ......

Correct, also the mosfet warmth was because of too low bias.
On lateral mosfets designs today bias is set around 100-150mA.

Vertical mosfets aren't designed for audio, but switching.
I don't like the sound of them, because they need very high bias they have thermal and hysteresis loop problems.
I've seen many designs blow up are unstable because of this.
