We'll see.
I don't see a difference between '0 series batch for early adaptors' and beta. Anything found by these 'early adaptors' would be revised prior to production, so it still feels like a beta to me.
And I still don't interpret Jan-Peter's posts as an announcement of imminent production

Once again
... patience

On Monday my 5 NCore's and 5 SMPS600 arrived.

Here is a picture before the assembly of the first amplifier started:

Currently I'm waiting, hopefully tomorrow, for a hole cutter suitable to fit a XLR-chassis plug. So I can tomorrow evening progress on assembly of the first amplifier and do some testing with it. If everything works okay than the remaining 4 will be assembled early next week. (I'm going on a weekend trip with 3 friends without wife and children. That is something I don't want to miss...)

Definitely I would like to have finished them before my new speakers arrive. 4* XTZ 99.38 MKII and 1* XTZ 99.36 MKII.

Just need a confirmation please, if I am putting all this in one case, then I only need one smps for the two nc400's, and there is zero degradation in performance in doing so, correct?

There is degradation in total power. The SMPS600 is a 600W supply, so if both amps are working equally hard, you will only get 2 x 300W output (as opposed to 2 x 400W if you have separate supplies for each amp).

Is actually capable of a consistent 400 watts? Someone suggested it might be closer to 300 watts rms

True only if your signal is a highest-level, in-phase high-duty-cycle signal = unlistenable test signal. For a more typical music signal, the addition of each channel drops the max output voltage by an amount related to the crest factor of the signal.

Start worrying after 4-6 channels...and adding filter caps is an option, or would be if there were room for them. If you want better channel separation, well above the absolute floor of 85dB PSRR, you should get more PSs.

+1 for Marchand
http://marchandelec.com


I did not hear any coloration with MG3.3 and MG3.6 and I heard incredible improvement especially on the bass but also on the mid-highs.

I had ordered from them an XM9 and a bunch of mounted resistors to be able to experiment with a range of crossover frequencies.

Interestingly I was only able to satisfactorily match it with a REL subwoofer after I got rid of the original passive crossover. Before bi-amping the magic did not happen.

The DEQX HDP-3 and HDP-4 add speaker and room correction (analog or digital in and analog or digital out).

The Marchand kits can be bought pre-assembled or DIY.

Hi Mjock3, I'm using these cases: A18 Black Full Aluminium DAC Case Enclosure | eBay

Sure - I was just being conservative and going for the worst case scenario.
