It's nicer looking and has better performance than a ribbon + an adapter board on top of the module.What's the point of this empty board?

Painted. I have to admit that I got some inspiration from the computer builders. Except the RGB LEDs .Is the inner case painted/powder coated rather than anodized? Not sure how else to get such a large area of bare metal.
Lovely build though, inspiring for us DIY'ers.
Sheet metal work looks very nice and clean. Nice job.Painted. I have to admit that I got some inspiration from the computer builders. Except the RGB LEDs .
I think the holes keep the surface area pretty constant, if not even reducing it (plus reducing thermal intertia by removing material!).Many holes are drilled which increase the surface area of the case to allow better convection cooling.
The 3409/N2 is based on one Hypex NC252MP.Looks like boXem has more powerful models https://boxem-audio.eu/en/5-stereo-amplifiers
I wonder which Hypex modules are they based on?
judging from prouduct descriptions, possibly https://www.hypex.nl/product/nc250mp-oem/74 or https://www.hypex.nl/product/nc252mp-oem/76
and https://purifi-audio.com/eigentakt/
it's a bit strange that the most powerful model is from a different family, not ncore.
What circuitry is on that board? I cannot see any components.Yes, it is an io board.
That's because there aren't any. It's literally a fancified cable.What circuitry is on that board? I cannot see any components.

Why better performence?It's nicer looking and has better performance than a ribbon + an adapter board on top of the module.
I'll await boXem's response, but can report anecdotally that I spent most of 2020 hiding out at high altitude in super-dry air - 8% RH was typical - and I had three disparate things fail. The only thing in common was ribbon cable inside of each. Static buildup, I assumed. Would love to know if that's a known issue, or just unlucky.Why better performence?
But there is already a ribbon cable in-line to that PCB.I'll await boXem's response, but can report anecdotally that I spent most of 2020 hiding out at high altitude in super-dry air - 8% RH was typical - and I had three disparate things fail.

Already replied few posts above. There is a groundplane to shield against el. field and also prevents capacitive coupling.Why better performence?
But why not just use a twisted pair or even shielded cable to connect the input PCB with the signal detection circuitry directly to the amplifier module?Already replied few posts above. There is a groundplane to shield against el. field and also prevents capacitive coupling.
