jaxwired:bananas will definately sound more open and airy, but you have to make sure you rub them on a unicorn's horn first. Also, very important to use vertical strokes...
They will, but ONLY if you use gold-plated plugs using gold from South African Krueger mines. The lesser rated South American or Philippino variants of same will result in a tighter, but some perceive this as boxy, sound. Pros and cons to both naturally, and I stress, this is my opinion only.
Have you considered Norbost Platinum as an alternative? Top end plugs, £595 for a set of eight, best used with Cable-Talk 3.5 bi-wire. The results are indescribable.
