Solid State Amplifier Advancements In A Decade

"I really haven't seen a major technological improvement in circuit design. regulators, power supply, circuit topology, etc. no real major changes. Just better components, layouts, etc. And as I wrote earlier, better transistors."

The above statement is pretty much what I believe is the case in the last 10 years, and is the reason that I created this post.

Can anyone refute the above quote?

Kr4, thanks for the link. I read the review. I wonder if that technology can be scaled to create an amp that can play at 500 wpc or 1,000 wpc at 8 ohms at attainable prices.
