I've just ordered some new B&W 603 S3 speakers, and I'd like to know what speaker cable to use. If you own some 603's, what cable do you use? In the shop, I was shown lots of different Bi-wire cables, which ranged in price, from £5 to £40 a meter. Bi-wiring is new to me, and I've never bi-wired any speakers before. If you own 603'S, do you bi-wire your 603's, if so, how does it compare with normal wiring? At home, I have 2 brands of speaker cable I can try, QED original, and Monitor studio. Both types are for normal wiring only. I'm using a Yamaha RX-V640RDS receiver. Thanks for any advice you can offer.
