Amplification: what are the biggest advances of the last 40 years?

As an audiophile most of my adult life but without any engineering expertise, I wonder how amplification has advanced since I started in this hobby as a high school student in the eighties?

Specifically, what has advanced the state of the art and what, specifically, make newer products sound "better" than older ones?

Is it that circuit design has advanced so much?  Or is the bigger difference parts quality and the technology leading to these better parts?

And please, none of the banal "it all matters" comments.  What I'm asking: which of the above matters the most?

There are better parts and a lot more of them on the Boutique side.

Class D amps.

The greater usage of BIG valves. The 300b is being used everywhere.

A lot of development in bigger power valves, KT90-170.

AND top Top TOP of the line amps. Valve and SS amps are just art work inside, a lot craftsmanship..

Sure are more than a few I'd like to test drive if nothing else..

Yup thing have change. I think for better and a LOT of them run a lot cooler, valve amps like the Crimson 275 and all Class ds.
