Gold?


Probably a nickel plated brass core would do.

Ok for nickel /brass

Our noise circuit was finalized...(active). In simulations we get 40-50db in 0-20Khz, about 30db at 100Khz and 20db at 200Khz.Of course we have also passive filtering (LC).

We are pretty sure to have excellent noise specs output and input (mains)

If you want tor reach "Best" cable and connector, it should be nano tube carbon. it conduct like copper and acid resistant as glass, also strong as steel. gold are soft.

If you say so. That's the reason I said to keep it DIY-friendly. This way we all can use our
own favorite wiring - just in case.

Price/Performance ratio will be one of the key aspects. For now Allo has shown to
come up with good quality products at reasonable prices without using boutique parts.
From my perspective I think that's a good approach.

Yeap I think we will skip the nano tube cabling...

One issue we have, is that mold manufacturer is saying that plastic casing has to be glued. So customer cannot open. I think its best to get the cables correct from the start.

I don't see a way to open it.

Ok. That's the same issue I have with the iPower.

A jack and/or a screw terminal right at the PS (without any cable) might be the best option to avoid
destroying the case. You'd just have to add a separate cable to the box.

Are you serious about this? In case you are I'll comment on that content.

One question...on our rectifier bridge we are thinking to add snubber to reduce the EMI.

Instead of using RC snubbber on each diode , can we use only one before the bridge ?

Something like this https://diyaudioheaven.wordpress.com...es/snubbering/
