Hi,
(TL;DR: skip to "The main question...")
I'm planning a hobby project to build an all-digital surround/hi-fi
system. Regular surround/hi-fi systems convert digital input sources
to analog in the surround processor/preamp, but I want to keep the
signal in the digital domain as far as possible (by using all-digital
class D power amps, aka. "PowerDACs" [*] that convert a PCM signal to
an amplified PWM signal that is feeds the speaker directly through an
LPF.
...
[*]: Examples of all-digital power amps include the
NAD Direct Digital
amps (M2 and C390DD), the Tact True Digital Amplification series, etc.

Hi Johan
I have previously looked for such a product, with no luck--I started
to believe that no such thing existed! Do you have any more examples
that I could check out?
