Binding Post Jumpers - New Product!!!

I will report back after 200 hours. I am not sure I agree with your assessment of solder adding benifits that outweigh the proposed effect of micro arching at these low voltage signal levels. My ears and experience suggest otherwise. I am open minded however and perhaps in this instance the resulting sound is not compromised.

No need to thicken the material at all. Leave it as is and drill a hole for a set screw that is mounted in the outer plastic case. (Perhaps two) The screw forces the wire up against the wall of the material. Nice direct connection with no solder. The outer case will need development and it will cost more. It should be made to support the wall of the connector material.

I use WBT with 4% silver I believe. 

Just wondering, that’s what I used.

+1 for the 4% silver WBT

I've tried a couple of eutectic types, but the WBT seems to flow much nicer throughout the joint and leaves a smooth finish by comparison

Don't know if the sound is impacted when used on speaker cables - I've never tried an A/B comparison.

But I did do an A/B on KLEI RCA plugs on my IC's from the phono stage and the WBT was a little faster in dynamic performance,  so I've always used it from that point on.

With soldering I use a small blade screwdriver to apply a small amount of pressure on the bare wire being soldered (next to the insulation) while soldering, especially as the solder is cooling. This is to ensure that the bare wire and metal surface have very good contact and that the solder acts as a holder and sealer of the wire and metal surface (joint) and does not act as a conductor of the joint. It is not good to rely on solder as the conductor of the joint as solder is a poor conductor.  I find very high eutectic solder to be best.

When done like this, soldering is way better than screws and ensures that the join is held well and sealed, so that joint oxidation (etc) does not occur. Screws can damage the wire through pressure and the screwing action and does not prevent joint oxidation. Joint oxidation can also occur with crimping. Soldering, though, is usually a bit slower but if done well, very effective.
