Shall we simply buy original 458 together. Peanuts: just about €10.000 each of us. You can keep left channel and I take right channel and start digging into the subject. 😀So all that is needed is an original PCB and an X-ray machine, then?
(to follow traces in a multilayer card)
Seriously now: let's keep our NHB-108, listen to fine music and wait until Chinese do the job. 🙂
Interesting indeed,
For simulations here we use predominantly LTspice.
What we need here is a 100% copy, not just schematic but topology of the original pcb. .
So, in other words, unless somebody donates a $170.000 amplifier to someone with extensive skills AND an X-ray machine (to examine a multilayered card) there will be no 458/468 copy?

Or a Group Buy between 50 people here and examine/copy the cards 🙂
I. e. $170.000/50=$3.400 per person..
hmm

It is not crazy, it is creativity, courage, determination...What a crazy fixation this is...
As usual: "All You Need is Money"
The Chinese who cloned NHB-108 really purchased it, dissassembled it and made a clone which we use now.
HERE is the original thread where the "prototype" NHB-108 was unboxed, somewhere in China. Below is a photo of the "prototype before the unboxing.It is not crazy, it is creativity, courage, determination...

In post #7 on that thread somebody said "Do it as usual, dismantle it completely, then copy the board ~" and they did it. Awesome. That's a real "DIYers spirit", not simulation. 😀
Therefore this "single pair" Dartzeel NHB-108 isn't just a copy but a real 1:1 clone. All we have to do is to get a pair of bare boards, assemble it from good components, add a quality power-supply and make a decent chassis. This clone is not a poor-mans amplifier but has potential to be improoved clone in a decently designed chassis. To my taste, the original chassis is outright uggly. 😱

That is just silly. Why on earth would you need two?
Besides, as we know, there is a cool down period for anything you buy in the EU. Is two weeks of peeking under the hood not enough? Provided you don't leave ugly tool marks with your wrench set, there should be a full refund minus the shpping coming back. So, how about $10 per person? 😛

What??? 😱
Blasphemy!!!

I like it so much i even started looking for a new computer case in 468 style with a processor sink in gold 😛

Wow, that IS a great idea 🙂
The Law is the Law!
But, really, would it even be possible to reverse engineer the card without X-raying it?

Another option is to ask "the Russians" to hack a certain server 🙂

Chinese are crooks
I don't know, but to me it looks like Barby suitcase.What??? 😱
Blasphemy!!!

No offense meant, just a friendly comment. 😱

Yeah!Chinese are crooks
There are good and crooked cops.
There are also good and bad crooks.
It all depends from which angle you observe them.😉
Those who sold us these boards are good crooks. 😎
No way, the main hacker is on cold in London Tower waiting for execution ... I mean extradition. But whom should he be extradited if the crooked cop was fired because he was a Comey... I mean a Commie.Another option is to ask "the Russians" to hack a certain server 🙂

Sory for typos, but I guess you know what I mean.

Does that mean that many of us on this forum are aspiring crooks, as well?
Another way of looking at this issue is calling it Democratization: Enabling scores of people not part of the 1% to buy otherwise ridiculously Overprized stuff...

adason has a delicate sense of humor but has forgotten to insert several smileys for those who do not understand the joke. 🙂
He also is a proud owner of Chinese clone and seems to like it.



Is he affraid of before-dawn FBI SWAT raid with loaded machine guns because he broke Swiss IP laws?😱No, he sold it. No more ch crookery for him 🙂
