Ok, audiophonics delivery is here, now the questions start!
2 power supplies from one IEC, is it best just to solder 2 cables to the IEC tab (twist together to make 1) - 2 cables into a spade connector doesn't seem cool.
Any other solution that I'm missing?

Best way for dual mono (I shared it in previous thread). To get a clean cables management

But how are you splitting 1 IEC tab input into 2 ? are you splicing the cables ?
As you van see on graph splitting is done from PSU1 AC inputs ))) you double the cables from here easy-)

Check my dual Mono Bamboo project

I shared you the best easy practise... Why do make it difficult ? Less is more....
My cables are too fat to join at the jst connector and don't fit in a single faston...
I don't see how to join the cables :)

Show pictures and a diagram of what you want to do ?

I'm just giving you some DIY advice: I model all my projects on an A3 or A4 sheet before making them. Ditto regarding the implementation of wiring and soldering etc. I always carry out continuity tests and all this allows you to have an impeccable projection afterwards)

He is just looking for actual practical advice on how to connect the cables. Not theory and unclear photos.

@brunes any of the ways you have listed above will work great.
PE makes larger gold plated spade and fastons that you could get 2 cables into one, as well.

I agree and it is exactly what I did previously by sharing a super simple diagram to avoid any mess with all those cables --))

Thanks for the support!
I get the idea, I don't get the logistics of it :) I have 2 fat cables that I can't join at the IEC end with a FastOn connection or the SMPS/JST end.
So somehow I need to join 1 IEC tab to 2 cables.

The wago look good, will go with those! Thanks.

Can I ask about grounding :)
1x IEC Ground to case.
Should the x2 SMPS then ground to a separate grounding point?
XLR pin1 to chasis (ground tab on xlr)
(3e audio boards no specific grounding)

To help, Hypex recommendations :
I would ground both PSUs to same point.
