Spade vs bare wire

Hi,
@aberyclark, you can follow Kondo's approach and just tarnish with solder the ends, that would leave cable character intact.

Tinning is probably not the best idea:
 - Solder is soft and malleable, so connections tend to loosen over time and are thus not gas tight.
 - Tinning should be done in a solder pot
 - There are 2 dissimilar junction instead of one
 - Unless you are expert with proper tools and the correct solder, you run the risk of a 'dry' or incompletely wetted flow which are sonically awful.

Bare OFC cable is the simplest and easily the most convenient. Issues with oxidation, if they exist at all, can be dealt with a periodic clean once or twice a year.

Besides, concerns with any oxidation of speaker cable pale into insignificance compared to oxidation of cable used inside amps, speakers, the mains, the power station etc etc.

Maybe, but what about the potassium?

Pray tell, how do you clean multi-strand 12ga 7x24x34

Soldered connections are gas tight and don't oxidize.

Tremendous improvements in sound quality can be effected by removing ALL crimps / headers / connectors from the audio path and soldering the connections
