I am looking to gradually update my speakers, 1 section at a time. Right now I have Klipsch SB-1 bookshelfs for my left and right channel and I am thinking of upgrading to B&W 603's. I am just curious on the general consensious out there on the B&W speakers over my little bookshelfs. I am getting the speakers used and wont get a chance to hear them until I go pick them up. Basically are these speakers worth taking a listen to as it is a bit of a drive to hear them. I have a Harman Kardon AVR520 powering the speakers by the way. Thanks all. - Chad
