...thanks...I didn't get that far...I see it said "option"...sorry for the imprecision...

...I am trying to determine what makes them so much more expensive than Audiologic or Nord...

...they seem to take a hit @ 2 ohm compared to the reference design...

...if I can just wait a little this x module will be obsolete and less expensive...

NCx500 wont be available to early April now. So please be aware if this info is not posted on companies NCx500 ordering page. Hypex saying don't worry nobody has them yet.
Here is what I get every time I try to go to your site

A reader of ASR should be knowledgeable enough to add an RME ADI-2 DAC to this amp as endgame. Not many in the overall market though, I agree.
What passive speaker with passive crossovers makes use of that sinad.
surely better off with genelec or Neumann integrated product with measurements.

Can someone recommend standmounts or floorstanders to pair with this amp.
I am trying to mimic studio monitors, flat frequency response with some eq.
which passive speaker is worthy?

Thought I would share a THD+N measurement at 4 Ohm we conducted of the NCx500 with the internal buffer vs our (Vera Audio developed) buffer. We are presently not offering an amp with NCx500 but we're considering it. Take note the measuring equipment itself becomes a bottleneck here when the distortion get's to the lowest levels, thus the distortion is actually lower.

Internal Hypex buffer:

Our own Vera Audio buffer:

Higher resolution from 100W:

And below we can see the Vera Audio P400/1000 with NC500 modules. With lower wattage, it measures with lower distortion compared to the NCx500 with the internal buffer.

That looks like a significant noise reduction.

To anyone wanting to upgrade NC500OEM modules to NCx500OEM, Nord already has them for sale.

Appreciate the heads up - the old/original 3 channel NC500s I have do not leave me wanting for anything else, but curiosity always hits ...

Glad to see love back to Hypex

Only for sale if you have a Nord NC500OEM to replace...

Makes me proud of my home town Groningen where the company produces.great stuff!
Hey I am planning to go stay there this summer on a "tour" of Luxembourg, Netherlands, Belgium. What are your favorite places to eat? Best area(s) to stay (i.e. walkable to restaurants and so on)? And hmmm is there a factory tour of Hypex I wonder...

Isn't testing this unbuffered a bit unfair for comparison? How useful is a power amp with just 12 dB of gain and what is the input impedance in this config?

Can these be configured for 23 dB gain?
The NCx500 OEM amplifier module has an on-board high-end buffer stage which is jumper selectable (J15/J7) and allows for 26.8 dB of voltage gain, vs.11.5 dB as tested here. This a great match with the miniDSP SHD, providing ultra low noise & distortion, with immense power.

How is SINAD changed with such difference in gain?
