Amazon Customer 3 Sound quality is fine up until the plugs have a critical failure (and all mine did)…. the pins separate from the body of the plug… this happened on ALL four of my speaker connectors and with two different pairs of speakers (one Dali and one B&W)… they were not disconnected often (maybe 3 times over the course of a year)… so I am very disappointed. You CAN put them back together… but they are not soldered… it is just spring tension holding them together… not a good design. Will not buy again. Too bad that, as they look very nice and sound fine otherwise… but when the pins fall out they stick inside the speaker terminal and need to be removed with needle nose pliers making the whole convenience of a banana plug worthless… and once they even came disconnected on their own… not good…
