Unplated copper spades/banana

This same question can be applied to power receptacles and power cord plugs and IEC ends. It's not a matter of one being better than the other, they are just different. I comes down to personal preference and what you perceive as a good or poor match up with various combinations of wire and the connectors. Also, a specific combination of wire and cable can be perceived as good on one component and less good on another component. It's variable.

Re: the tarnishing of bare copper, well, if you have a strong preference for how a bare copper connector sounds, you will likely be willing to have to do some periodic maintenance to clean it. Spade = best chance for better sound, Banana = more convenience.

I guess my question is, what does bare copper sound like vs gold plated?

Loss of warmth?

Increase air or detail?

Thanks

I’d like to hear from someone that has done detailed comparisons as well.
