Welborne Labs house brand is better than WBT and as good as and cheaper than Cardas (which they also sell).

Best Solder
I'm a little confused. What is the best solder? Johnson IA-423 (John Manufacturing), wbt or cardas? I'm about to start a project and the audio community experience would help. I was going to use cardas, but the Johnson has a high silver content (6.5% or so and no lead) and I've been told the wbt is a little more forward compared to cardas.
