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.
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?
