For many many years I just rant bare wire connections from my amp to speakers. I just switched to a very neat array of banana plugs. When I installed the banana plugs I noticed the tarnish, grime whatever on the ends if the wires and what a mess it all looked. Now, I can say I noticed a big improvement in sound. My amp seems to put out more power that I can see on my meters, more definition, more high end etc etc. Perhaps the old connections needed the cleaning and retiring but I am more please with the banana plug connections. All looks neat clean and sounds better. That’s a win for me.
What say you binding posts or direct wire?
If I can get away with it I don't use BP. I find even the best like Mundorfs etc all sound inferior to direct wiring. Seems illogical to me to use costly cables hooked up to a binding post and then having just hook up wire after the posts. I get better-sounding results just by using quality speaker cable wired directly into my networks with the same cable type after to transducer.
