Absolutely guys, a feedforward error correction of a class D with a lightweight but extremely linear class A is doable. But, given the OP's demonstration of different amplifier topologies, he/she has a LOT of studying to do.
As far as a need for such error correction, given how good many monolithic class D amps are, is that multiple order of magnitude increase in complexity (and need for precision components) all that beneficial?

You won't know until you try it, that's why we are here!, those who question matching, cost and benefit belong in a marketing conference
Hi,
Depends on what your arguing about. Build a small class A that sounds nice.
Turbo it using feedforward with a Class D amplifier. In theory using the
feedforward topology the Class A amplifier will fix any faults of class D.
Its only a matter of time IMO that valve + Class D will be common.
Not for ultra low distortion, but for a valve sound with some juice.

Cheers.
Do understand, no less, that I do enjoy absurd overkill for its own sake, but at the same time, I'd enjoy helping others actually *finish* projects.
I have done current dumping, I listen to my home brewed complementary output stage quad 405 based circuit.
Class D plus error correction is next on the hit list, but since the COD 405 sounds so good, its not a priority.
