The major difference with audio is it's based on listening. Without listening it's meaningless. Once we cross the threshold of where the specs are so good many will consider perfect, it's personal taste that determines the rest. Personally I don't like the sound of poor measuring gear. I prefer the music. But i'm not so naive to think that there's not differences in sound among the top measuring gear. If this was the case we wouldn't be offering many options of stellar preforming discrete class A opamps. Because we know no matter how great they all measure, they all sound different.

And how do you (is that a royal "we"?) know?
(I suspect this will take the thread into endless off-topic rambling territory again, probably ending in need for moderator action, so feel free not to answer)
The point is how interesting it is.
By mere coming up with another high tech discrete op amp, and so called super power supplies (by the way almost 1 mV ripple is nothing special...) I am not yet convinced.
I understand that there is some competition going on on how to "improve" NC500 based amplifiers by tossing around with input stages which has to be discretebut it remains to be seen if it all leads to a better sounding amplifier. It's a very commercial affair.
I suppose everything remains to be seen. Just the same as how just over a year ago in this thread when I unveiled the NC-500's and shared with Boggit my early gen buffer design based on discrete class a opamps. What was seen following that was a revolution in class D. He's sold 100's of amps to people who were class D haters, even after hearing NC-400's and Mola Mola's. His original plan was to just use the stock Hypex LM 4562 based buffers. Had he did that I can assure you Nord wouldn't be where it is today.
Now he's decided to even copy my cases for his amps. Let's hope that takes him even further.
Agree: by saying that you actually confirm my scepticism. By just coming with high spec devices you will not make it.
If there has been a "revolution in class D", it is due to new designs such as nCore (and the understanding and insights leading to them), not because of some small-volume op-amp buffers.
It's like saying "after the war, air travel was revolutionized by the use of round windows in the new jet aircraft, compared to the square windows on the DC3".
Scroll back to Oct 2015 on this thread, Read what I shared back then. Look at the end results today:
Nord One Up Ncore NC500 amps, Class D ready for prime time .....
I convinced Joe the mod on Audioshark to buy that amp. Read the entire thread front to back. This is proven results. We are 7 gens past that design now.
Mmmm...revolution....
Ncore, improving on the sound quality level of class D amps when compared to UCD and other "mediocre" sounding class D, can be called sort of a revolution (though I'd rather use this term for other, more important and non-audio related things).
Real world sales figures and results matter more to me than peanut gallery bantering with nothing backing it.
The NC-400 was released in late 2011. It's a phenomenal amp, but it didn't appeal to everyone. It wasn't until my input buffer design Colin used in his Nord amps that class D haters finally turned a new leaf. This was 4 years after the NC-400. Read the Audioshark thread. This thread put Nord on the map:
Nord One Up Ncore NC500 amps, Class D ready for prime time .....

Even today Ncore amplifiers, with whatever input stage, don't appeal to everyone. That's simply how audio works, because it is, like most things in life, a world of objectivism and subjectivism.
I am OK with your enthusiasm, but it does not imply that what you have is "best".
Indeed. A hundred units sold is truly peanuts. How many nCores are there out there in total? How many other class D amps?
Let's reserve "revolution" for real, significant changes in the industry/market, not peanut stuff.
I'm not sure how many he sold. But there's more talk about the Nord's around the Internet than any other Ncore based amp lately.
This seems to be true - you happen to be everywhere talking about the Nords.
Why are you seeking approval for your commercial products on a DIY site? Are you so unsure of your implementation decisions that it is necessary? Or is it hidden advertising -> Vendor Bazar!

some dubious text book front end buffer was the revolution.
Ncore Class-D architecture by Bruno was the easy part.
The said "revolutionary" buffer also beat the discrete buffer Bruno developed for NC400.
I dont know about others, but i'm convinced about Bavmike's contributions to advancing the state of the art in Audio.

Yes Hypex has made the amplification end very easy. Getting positive feedback from a wide variety of previous Ncore amp haters meant doing things different than making a carbon copy of every other Ncore amp on the market in a different case.
