I have this happen every time I unhook wires or have to mess with the springs under my speakers. It takes a couple days.
I have ribbon speaker wires and spades would not stay tight so I had new ends installed.
In the mean time, I bought Chinese speaker wire. Silver coated copper with Rhodium coated banana plugs that tighten down and expand the banana once inserted. I had previously tried interconnects of the same wire and liked them. So I purchased the speaker wire. At first I said, detail, crisp, accurate, etc. I have had thse wires for a month. I feel less enthusiastic currently, it sometimes sounds conjested or muffled. I think there has been confirmation bias, burn in, different recordings, volumes, etc. So it can be confusing as to what is going on. I plan to leave this wire for awhile before I put the ribbon wire Beckwith the Rhodium bananas.
