Referring to binding posts on speakers. But if one wants I could see where a soldered connection no posts on an amp would most likely be an improvement it would just be a bit impractical to have to desolder amp from speaker to move it. A directly wired speaker is easy to move just roll up the cable. I can see where most couldn't explore a no-posts direct wired speaker but if you DIY a speaker it's a great option to explore. I tend to use fairly high-quality wire when I do so and keep it all the same and eliminate the many extra connections BP requires.
