What is this? rectangular PCB like nc500OEM. Title is a little ambiguous as to whether this is Hypex or for Hypex, but ncore label is clearly on the PCB, as the writing NC400OEM and V0.1 (which is also not how Hypex usually label their versions).

NC400OEM is an older (discontinued?) OEM only product from Hypex. Please see this post and the following ones.

@Karu switching to Nc400 will ensure that your speakers have no sound. ... :) Is that a good thing? :eek:

That's the NAD licensed module for the M22.

They are now all over the place on Aliexpress, ebay.com, ebay.de. Did they find a container of NOS stock? Is someone manufacturing thew, as in new illegit copies?

It looks like the mounting holes have traces of screws.
So these could also be disassembled/used/repaired modules.
These are more common on AliExpress than you might think, as are high-quality disassembled components like op amps or transistors.

I once mentioned such an offer to Hypex and they told me that the module's serial # was several years old and probably already used. As @dedobot and @Roland68 just noticed.
