Well that's interesting... Hypex changed the pricing policy very recently, I take back what I said, either that or competition creep.

Nobody would have an issue if Hypex did the same.
Not sure I follow how they were using the nc400 on this DIY forum as an advertisement for the nc1200, which was not and is not available to the DIY crowd.

In any case, Hypex and the Soekris company aren't even close to being in the same league when it comes to professionalism- delivering tested, debugged, ready to use products and standing behind their advertised performance. The nc400 was sold as a DIY product. When a problem arose, they said "just send it back and we'll repair or replace". When issues surfaced with the Soekris dam, he said "fix it yourself, this is DIY". It's a cruel joke.

"I think everyone can agree Soren originally oversold the dam1021"-- you think? Little good it does people such as myself that bought 4 original boards based on his "oversold" advertising that the latest and greatest, rev. 5 or whatever he is up to now, finally deliver what was initially promised. The latest shoe to drop concerning potential synch issues is just another kick in the jewels.

What now ? please, what's going on with the Soekris DAC ? I've been planing to use it in the future on my diy r2r dac. I'll admit, I've not dug deep into this product, just found it a few months ago and thought, well, that could be interesting as diy dac.

The latest versions appear to have cleaned up the issues from the first version so you shouldn't have to worry. Lucky you.....

So what issues are you aware of that Hypex has ignored or told you to fix yourself?

I'm not aware of any inherent flaws that compromised the module and prevented it from achieving it's advertised performance. What's more, knowing Hypex, they have always been quick to resolve any customer issues in a completely professional manner. In my own case, when I needed a new set of connecting cables, due to my own mistake, they sent me a completely new set, for free, not even charging me postage. They know how to put the customer first.

Ran the simulation of the NCore design .... that is truely impressive .... and way much better performance than the original UcD ..... would say it's in a class of it's own ... wow

Thanks analogspiceman for the simplified schematic .... much easier to follow ... briliant

The original 12 transistor(s) making up the comparator needs to be deconstructed as well, I have a feeling the external poles/zeros is targeting that comparator design.
