I'm thinking about getting Wharfedale Diamond 9 speakers as a full surround package. However, i wondered about the cabling. Are there any speaker cables supplied? Will they have banana plugs on their end? Is the standard cabling good enough to enjoy the quality of the speakers, or do i have to invest in ultra high quality and costly calbing to really get the best sound? If i do have to buy good cable, what cables am i after getting for connection (of front centre, front right, front left, sub, rear right and rear left) to an amp? Will the QED Silver Anniversary XT cables suffice? Does the cable to the sub have to be different? This is all a bit confusing.
