You are carrying small amounts of current and the yes there is micro arcing when you don't have tight connections.The net result of whatever it's doing,it's increasing conductivity because there is a noticeable difference of what is being heard coming out of the speakers..You know well enough that I don't buy into the snake oil crap and it has to be really something..
Honest amplification is better than excessive 2nd order distortion anytime.

"...because there is a noticeable difference of what is being heard coming out of the speakers."I'm not disputing that.
What if you have a solid connection but the conductor ends somewhere.
Let's look at spade connectors, the flat part is tight and a good connection but at the edges the metal pulls away. Is there micro arcing where the metals begin to not touch tightly?
The same can be said for any mechanical connection. Maybe everything should be soldered.
It would be interesting for you to listen to and measure with all connections soldered.
But the connectors should be soldered all the way to the edge so that no portion of the connectors, that are in close proximity, are left un-soldered otherwise micro arcing might take place.
Imagine a wire tightly wrapped around a solder lug. The wire has to leave the solder lug at some point. What if you soldered the wire just where it's wrapped tight but not where it starts to leave the lug. Would there be micro arcing there?
I hope you see what I'm trying to say.
I believe that if you have a good connection between part of the two sides of a connector (that is a large enough area to carry all the current) all the current will flow through that good part of the connector there will not be any current trying to flow through the part of the connector where the connection is bad.
The difference you're hearing and measuring has to be something else.
On the other hand, I could be completely wrong but someone's going to have to show me why.
P.S. If you didn't have a 'total area of good connection' that was large enough to carry the current before treating, then I could see micro arcing taking place over the rest of the connector area and that would end if the treatment enhanced the connection. But with signal wires, how much current are we talking about and how much true contact area do we really need? I would guess something the size of the head of a pin.

I don't dispute that either..We do have solder helping us there and ,we are dealing with the higher voltages many times on the terminal strips.
I also took some unused RCA Jacks over at the same time and that's where I noticed they also looked like rot under a powerful microscope with all the imperfections. Kevin worked in the metallurgy dept and that's how I knew he would have knowledge of this type of stuff..
Tre,it's a half ass solution but working in the automotive industry,I see all kinds of imperfections in metals such as heads not being ported ans polished correctly and the tiniest distortion in the intake ports can change the dynamics of the air-flow by a good bit.While one is mechanical one is electrical,it does make us realize that small distortions in the metal can be a big issue in certain applications.Basically the SilClear is creating more conductive contact area between two points on each connection..It doesn't permanently fix the metals but it does allow more flow of electrons when you have more contact area.
