Class D amps seem poised to take over. Then what?


I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

Class D has already taken over. There are more class D amps sold than all the rest combined by far and their market share is growing while the rest is shrinking. I'm sure boutique brands will be available to those that want them.
Yes and more Corollas are sold by Toyota than Supra’s .

Perspective…. 
Class A amps are appealing, less heat, lots of watts, good specs.  Will they drive difficult loads?  We buy speakers that require the current and then see the price of an A or AB.  I'll keep my XA25 and efficient speakers.  House not heated up and electric bill is virtually the same.
