Default Internal PCB to Wire Connectors ?

Which type of "Pcb to Wire" connectors do you prefer to use for Line Level audio signals, when connecting several internal circuits together?

Soldering the wires directly on pcb is ofcourse the best solution, however it's not always practical, e.g. when you want to test modified circuits etc.

Both AMP and Molex have several ranges in .1" and 3.96 mm pitch that are good. The main problem on a DIY level is the tools, ranging from 1000 kr. and upwards. If you can take the cost, you just have to choose one, and stick to it - Molex is maybe the most widely used ones.
For myself, I work in the trade, and can choose almost what I want for my own use, since we already have the tools at work.
For occational use, one can get by using pliers and careful soldering, but it's fiddly, at best.
Without special tooling, it's only the IDC ribbon cable type, that's fairly easy......not much help, i'm afraid......

Wago connectors are quite OK. Ribbon cable is also OK.

Ah- yes, the Wago "rekkeklemme".....probably best for larger cross sections and higher currents....
BTW- I forgot about Phoenix - there is a large range of connectors where the cables are fixed by screws, with matching PCB connectors- quite good, actually

Those Wago connectors (there are also smaller 0.1" types) are excellent for small wires, any wire up to max area will fit with perfect function.

My favorite is model 256
Example here

Any magnetic materials used in these?

You have a steel spring in all cage clamp connectors, desides that they are are made of pure copper.

As you may allready know, I'm fond of the Wago's. See the attached pic
I also like molex, however I only find these suitable for PSU connection etc.

There's Molex in fine pitch. too..
Ampmodu is another alternative.
Wago and the likes are OK for a few wires, particularly power level currents, but I really find them too fiddly when there's a lot of wires - my personal taste, though....

What may be important if you publish circuits for others to build, is to use a pin pitch that's widely available. Then ppl can make their own choice based on availability.

The layout I make is always compatible with WAGO/Molex/Direct Wiring Soldering.
That should cover most of the demands
