People seem to like the sound of 1950's-60's McIntosh tube amps ... what material were they using for connectors.

Years ago I looked inside one of my Krell amps and they used a 1/8" copper bar from the circuit out to the speaker connections. And my Classe amp uses copper bolts for the speaker connections.

All those coatings must be like roadblocks/speedbumps to the music-making electrons making their way through your audio system.

Agree...

All that goes away with a metallic alloy fluid.

There is no surface anymore...

Lattice, structure, surface...and all calculations you know, and can get at least some handle on things via.... all gone.

If I just have to plate, though, it's PC-OCC, with a bath type draw through silver electroplate.

The PC-OCC should be very finely polished, first. Silver purity becomes paramount, in an electroplate. Among other things.

Not sure that plating really has any significant differences other than durability and resistance to corrosion??
We are talking about a few microns of a material that has resistance that may vary slightly from the cable that is many thousands times longer.
The total resistance difference would be many thousandths of a per cent in value and I would think be negligible.

The field interactions/shifts with the given lattice structure of wire, occur primarily, at the surface, with regard to change from one state to another.

Think of the surface of the wire as a light bend point, when focusing light through a prism. It's technically identical, in some critical ways, but we can't see the 'electricity', whereas we can see visible light.

Rest assured, a similar effect is happening but we have no visualization reference like we do with the prism and light. Heck, we can see the light and prism effect directly and have a good reference but we still can't deal with visualizing different configurations very well. Turns out this is important as our memory and recall systems are visually oriented, holographic, even. Eg, Elon Musk's eiditic (perfect recall) recall is visually based.

In the case of the wire, the surface and the dielectric and the air, we end up with some dynamic flow that is akin to stacked air gapped prisms.

Good luck visualizing this (below gif) in ac form, across a large, nay, huge spectrum of great wavelength change, and integrating with three material surfaces as a stack and totally differently shaped/geometry.

The better designers of wire looms for audio are aware of this great level of complexity -in what looks simple- but it is difficult to transmit it to the average person. Many people use the word electricity but very very few actually understand what is going on.

an example of this is how we can throw a rock and come up with the math for ballistics. And that math can be accurate and function and good enough to survive in the worlds that employ the aspect of science called ballistics. But ballistics has no frame of reference to the real science of what is going on.

The real science of thrown rocks... involves time, space, gravity, inertia, quantum systems of all kinds imaginable and a bunch of stuff we still don't understand.

Electricity is the same. We've got the equivalent of a good simple day to day method of working with it, and that's college level math and electricity texts. But those things have nothing to do with an explanation of what is really going on.

You'd have to get to the university research level to try and put human hearing in the same room with subtle wire changes affecting what we hear.

Most here would never admit that they have, or have had Nickel Plated connectors/receptacles...
