Finally, The Class D Holy Grail?

Any amplifier output is a scaled approximation of the input.  If it is the modulation in Class D that bothers you, I wonder if you feel the same about sigma delta converters, DSD, etc.

 

I think I share your general point of view, though.  If the best Class AB amplifiers (e.g. AHB2) can provide comparable or better performance than the best Class D amplifiers, then I'd rather not have the switching noise even if it is not causing a problem.  Especially if the Class AB amplifier provides this excellent performance while also including Class H efficiency.

 

Rather than chase after lower and lower THD+N, I would rather see Class D advancements where the switching noise is made significantly lower.

 

Any real life examples?

Sorry, I don't follow you.  Examples of what?

Examples of Class AB amplifiers with Class H efficiency.
