If you have banana plugs and bi-wire speaker terminal this product just provides an easy method of connection them AND they are extremely good at what they do.
The advantage is that the Banana plugs used on them are extremely well engineered and work very well
I use the Bananas on my cables and they provided more of everything across the board - I could not believe what I was hearing from a "simple" banana plug
Sorry I could not provide better comments
