Class D is like a DAC. They keep getting better as the tech improves, making older generations obsolete.
Class A is a much more mature technology, with better often times being different. The best Class A from 30 years ago is better than the best Class D of today.
Class D only exists for efficiency. Square waves and pulse width modulation is not hifi. Why bother with a bit perfect source signal if you are just going to chop it up and filter it...leaving behind some of the good with the bad...resulting in a thin hollow sound?
