Compiling a list of Power DACs / full digital amplifiers

[kandamrgam]

I think this can be summarized as "the best performance is making the DAC great and followed by a very clean power amp"???

As for "what is actually analogue and what is actually digital" to ME a "truly digital" amp would not have any separate D/A conversion inside. It would itself be a DAC capable of high power.

I was going to start a thread like this, mostly out of wondering if anyone had made a PCM (not PWM!) power DAC, volume adjusted I suppose by changing the full-scale voltage rails. That would seem the "purest" way to convert, which is not necessarily contradicting what Putzeys said about real-world design performance.

What are the problems/limitations of PCM-to-PWM conversions? I'm sure that has been written about...

See the ECDesigns models listed. It is exactly what you are asking for. Putzeys does mention in the article:

One should ask the question: would any D/A converter designer in his right mind build a DAC using power components? Probably not

Not sure how to interpret it.

It's pretty obvious though

Jeez just the abstract is enough to make me go out and buy vinyl! OK not really ha ha...
