Class D is still awful. The end. The damn things are built backwards. with the most important part of the signal being ignored and the least important exalted, in the measurements and the design.
That’s what happens when engineers with incomplete questions and data sets, go out and try and improve the qualities of said poorly informed question sets. They arrive at the wrong answer and a poor device regarding it’s intended solution point.
Digital is no less the same.
Steady research, sure..... but still the wrong question and answer set.
Another point is that class D in high end audio, may start to go away, as the BASH patent has expired as of last year. A dynamically variable power supply rail with a regular output device design (class AB, etc) is probably better, overall, re what part of the signal the ear works with. Class D makes a mess out of that all important small area. BASH, as a high efficiency design, harms it far less.
Class D would still exist as a widely disseminated type of device, due to it’s unique ability to fit smaller devices, reduced power levels, etc.. but BASH might come to dominate high end audio as the efficiency champ.. when played against Class D.
One might even claim, conspiratorially... that current or overall Class D design is an effort to get past the BASH patent. A poorly run effort, a compromised effort...with worse results.
IMO and IME, there is more unclaimed and unrealized high fidelity hiding in the BASH design than any current or known, or expected class D fundamentals in design.
When BASH arrives in high end audio, then the walking back of Class D may take place. IMO, count on it. Meet the new king, etc.
