Paul, the WBT low mass are as close to soldering the speaker cable to the crossover wire as you can get. If you look at a pic of them you can see it's a copper ribbon that is gold plated. Instead of soldering directly to the WBT you can actually put the internal wire sideways on the ribbon and fold over and then crimp the connector, and only add solder after. It's a great sounding connection.
Binding post replacement suggestions
Trying to keep price around $100 for a set of 4 post. Did not realize there are so many materials and coatings involved in binding post. Looking at Cardas, WBT, Vampire, maybe furutech. I don't mind cleaning post ever so often if I used all copper with no coating post. Any suggestion best bang for buck post that will not alter sound just provide less veiled sound without having to solder speaker wire straight into crossover wire, thanks
