You have no proof you built a class D amp. I could say *I* built one !!
Now, it's not "marketing", it's "magazines". John Atkinson and Robert Harley were "taken" by advertising. I don't think so.
Digital amps are the future !!

Don't confuse the situation with facts huh?
I'm sure it does not matter how many awards I've gotten (about 35 or so) or how long I've been in business (over 40 years) or anything like that. You'll go with someone that writes instead of someone in the industry that actually makes amps for a living. Because you have to be right.
It'll be interesting when someone actually makes a digital amp.
From the link below:
Footnote 1: The D in class-D does not stand for digital, as some commentators have suggested. Rather, D was just the next available letter in the alphabet when amplifier circuit topologies were being classified. A class-D amplifier can be either digital or analog in operating principle.
The author, John Aitkinson, happens to be misleading in this comment, as there is no such thing as a digital amplifier. If you change the last sentence above to read " A Class-D amplifier is analog in operating principle" then the entire paragraph would be correct. How about I see if we can get JA to weigh in on this?
Mmmm...John Atkinson 'misleading', I hope he sees this.
You're the only person who says "no such thing as a digital amp". There is.
Now a schematic, which eschews analog stages. No wait, this is phony too !!
I've spent some time on that site in the past as it often comes up in Google searches. I would direct you to other portions of the site which refute your claims but since you've not read a lot of that sort of thing in the past there is no expectation that you would do so now.
JA would be welcome in the discussion. I'm sure he can clarify.
Can't refute the page I linked.
Atkinson and Harley have enough credibility, they don't have to 'clarify'.
By causing this thread to 'spiral', you pulled more attention to it. Thanks to you, they'll now be a buzz on (true) digital amps...
If you're claiming that the amp at that thread is a digital amp, well it uses analog process to do its job. Quite literally there is no way it can't.
This is true of any amplifier that can drive a loudspeaker.
If a reviewer that has never built an amplifier before wants to contest that, all that happens is he's wrong. In JA's case, I'm pretty sure he was using shorthand with his use of 'digital amplifier' and I'm also sure he would be happy to clarify that for you.
Did John tell you he would clarify ? These are digital amps, as the schematic shows...
