I have built Preamps and power amps of both types and prefer the solid

i also did long ago. i never much cared for designing analog circuits.

A good portion of solid state circuits are analog.

a much larger portion of them are digital.


Not in the sense of power amplification. A lot of integrated circuit
designers do the analog work inside the chip that goes out to the power
amps. The power amps are analog and will always be analog.
Just less analog design to do at that point.

Well, class D is sort of digitial (pulse width modulation).


The only thing that would be classed as I know is some IPS units that
put out staircase power for PCs... I don't like them because of the
problems they created for wifes iMac... makes it run funny at times.
Best not to introduce spikes to the iMac.
