Correct way to attach speaker wires... Wait, what!!!

Thanks guys. Hey Erik what is WBT?

Heat from solder can be bad for high-end wire that's why many higher-end manufacturers Just a use a quality crimp on connector I use Analysis Plus cables and they are by no means the cheapest they use a very soft brass pressed on terminations

Hi Autre, WBT is a famous German connector manufacturer.

All connectors degrade sound. All, regardless of cost. Bare wire is best. Do the comparisons and it is obvious. So, go with bare wire.

1) just clean every so often and no oxidatiobpn issues.
2) or just thin the stripped area - good option

You can buy some very good sounding tinned speaker wire from Duelund. Their 16 gauge stranded in cotton wire.  Makes great speaker cable and costs $10 meter.  It is tinned already.  You can buy it from Parts Connextion if interested. 

The wire of your choice cold welded (method used by Audioquest) to thin pure silver spades.  Tighten down but not to the point that you deform the thin silver spades.  Listen and enjoy!
