Some mention "No Noise".. Where have you been? My 1971 and 1996 Audire Fortes have no noise. Neither did my 1985 Audire model 2, 1990's Sumo, 1970's Phase Linear 400, nor my old $50.00 garage sale Adcom 535. Well, actually I had to orient the Phase Linear plug with the correct prongs in their respective outlet holes.
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?
