@julf The NC is more efficient (especially idle dissipation) and drives low impedance loads better. Future revisions of the UcD400 will incorporate these changes (the latest UcD400OEM already does).
Most listening reports that are already "out there" are in Dutch, for obvious reasons. I notice that some of the people waiting to hear third party reports are Dutch too so they might actually be able to read them.

If we who are so unfortunate not to read dutch, are so fortunate that some who can read dutch, will report in English what they read, we sure will be very grateful, indeed

Bruno, please spread the word, when you expect the next batch to be available.
As for the data sheet questions, it would be great if you could specify the expected current demands for the input buffer stage supply. It could be helpful for we who are to specify a linear supply.
- You have shared the voltage demands, but current may be relevant too, especially as you earlier mentioned that it was expected to draw a lot more current than the UCD series buffers, hence the need for a lower voltage supply than that for the output stage.
cheers,

The NC400 is mounted on a rond heatsink, mount this heatsink flat inside your case. There are holes in the heatsink with M3 thread for easy mounting.
The end of January we'll have the next batch available.
Bruno, you are not making my decisions any easier
Any guesstimates on the time frame for the improved UcD400?
So I guess people at the Pass forum must be really pissed off with Mr. Pass and his creations... They keep building his newest stuff!

Translation from the link provided by BMW850.
I am quite familiar with the UCD product line by Hypex. A lot of people are building amps with the UCD. It is my opinion that you cannot have a better sounding amplifier than the UCD at that price. But without taking the price into consideration I found the UCDs to be compromised. Despite the correct tonal character of the sound. I always found the energy from a rendition of live music lacking with the UCDs. To me the attack and the decay of this type of music is equally significant. And the UCD seemed to emphasize the attack more than the decay. (The borbely preamp in combination with the UCD seemed to restore some of that balance)
The NCore dots the i's and crosses the t's. Not only is the tonal balance, precision and delineation correct as we have become accustomed to with the UCD. But the "energy balance" is now also correct. The combination of complete and utter control and harmonic richness of the instruments grab you by the throat. All point sources (instruments?) remain rock solid in the same spot in the 3d canvas from the lows to the highs. The assembled listeners were clearly impressed. One after the other CD was listened to. And if you see folks writing down titles of the CDs you know all is well.
In other words a great product, definitely worth considering!
Probably the hardest part to translate was "mooi product". Literally translated it means beautiful. A beautiful product. But in English beautiful refers more to the look. In Dutch it refers more to the whole thing.

Hi Theodosis O
The NCore listening test was at my house.
You are correct that it was the NC1200 oem unit but Bruno told there will be not much difference in sound between the two.
We compared the units against an PassLabs clone AX200 with I already use for years and compared to al lot of different amplifiers also the UCD180 UCD400 and UCD700.
I find the PassLabs clone better sounding on my speakers the the Hypex UCD models.
But I like the NCore more than the PassLabs clone.
Yesterday I ordered 2 NCore and power supply's.

You need high quality loudspeakers to show the differences; as always it is the weakest link to be the dominant factor, and most of the time that is the loudspeaker.
Some OT posts removedLoudspeakers were I think Avalon clones, with hexacone bass driver in a low tuned bass reflex, and Accuton ceramic drivers for mid and treble; surely a system capable of demonstrating differences between amplifiers.
Source I don't know but will have been up to the task no doubt.
The Ncore is better than the PassLabs clone but in my opinion closer to the passlabs then the normal UCD.
Did I miss something
Cd player Denon A1 UGS preamp from passlabs forum with some small modifications which you can read over there.
Speakers are a Eidolon Clone.
