Like Fliz I tried it all. I feel the method of binding to the speaker ends is the critical part. Crummy connections = Crummyniss regardless of the chosen end.

Keep in mind that if 6-nines copper is important to you, then bare copper wire is continually oxidizing, and copper oxide is a semi-conductor (a diode). Guitar effects manufacturers use diodes to create distortion boxes. Silver oxide is a conductor, so there’s no problem with silver. I love the low-mass architecture and the metallurgy of the ETI / KLE / Eichman connectors and we selected ETI for our cables. There’s a bit of confusion over the 3 names, and if you’re interested in the genealogy, you can find it here: http://www.eti-research.com.au/the-original-bullet-plug/ ETI dispenses with the intermediate nickel layer found in many connectors which I refer to as audio jewelry - pretty stuff, but sonically lacking (you know who you are). How much the metallurgy contributes to their sound is impossible to say, since I wasn’t privy to ETI’s prototyping sessions. What I can say however, is that the connectors I’ve heard with an intermediate nickel layer have a characteristic distorted sound to them. The ETIs are silver over copper, BTW. Disclaimer: I have no commercial interest in ETI, but I do have an interest in building the best cables that we can deliver to our customers. ... Thom @ Galibier Design |
There is a vast chemical difference between tarnished and a metal's oxide. In a normal room environment, metal tarnishes, so the validity of the oxide conductivity is specious. Gas tight connections are best. Bare wire in a connector is a poor idea as it will tarnish. Gas tight connections can be effected with crimps, but require the proper tool, connector and wire. Soldered connections may sound a little different, but it is unlikely that the solder is the issue. There can be several dozens of soldered signal path connections in every device. Worrying about solder when there are likely multiple crimped and soldered internal loudspeaker connections is silly. A standard speaker connector with a well crimped/soldered ring or spade terminal cinched down with a nut driver makes an almost permanent connection. The two layer WBT are as good and don't require as much torque to keep tight. https://hackaday.com/2017/02/09/good-in-a-pinch-the-physics-of-crimped-connections/ https://media.digikey.com/pdf/data%20sheets/molex%20pdfs/tbo%20quality%20crimp%20handbook.pdf AND, AS ALWAYS, YMMV.
