<font color='#000000'>I recent purchased a pair of Cambridge Soundworks Towers on closeout (under $800 for the pair plus the matching Center Stage)- an amazing deal at the price.
I've been reading up on the cables, and if I'm understanding, a high quality zip cable such as Sound King is about as good as anything. I happened to have about 50 ft. of quality 12 ga laying around and thus was able to bi-wire at no cost. I can't speak to how good they might sound with just straight connections, but if your speakers are bi-wireable, and considering that it really costs very little to do it, I figure that it does no harm, and might do some good. I would not have considered the ability to bi-wire a deal breaker when speaker shopping however.
I've never heard anything that might indicate that bi-wiring would degrade the sound.
I would never consider spending $200 for a commercial bi-wire assembly.
I have to admit that even with my low end Onkyo receiver, these speakers sound very good indeed. I might mention that I grew up listening to live classical music, love jazz, and have auditioned a number of high end speakers including Paradigm (my first choice for a speaker upgrade, until the Tower deal came along) and B&W's- and would consider these Towers to be in the class. My next major purchase will most likely be the Yamaha RX-V2400, as I have a difficult room (a loft with an irregular shape), which should likewise make them sound even better.</font>
