Nothing in the audio world from the 1950s is much more than an antique. The 2020 something tech changes everything, including the functionality of Class D amplification. Earlier in discussion someone suggested that putting a tubed pre-amp in front will make it all OK. I now run a Peachtree Grand X-1 hybrid integrated with a pair of 12AU7s in the pre-amp section. This is supported by 440 watts per channel of Class D transistors and this is a marvelous machine for a home system. Smooth, able to wisper and bang a gong. I do not believe most (any) listeners would be able to detect a real difference.
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?
