Biwire questions - Best cable for


New pair of B&W Nautilus 804. Krell KAV 250a and Lexicon DC-2 pre. Suggestions for biwire speaker cable for about $300? I need 20ft cables (or slightly longer). If I need to spend more, I will, but I'd like to spend no more than 3-400 bucks. Thanks all! Appreciate your help!

Fam, with all due respect, if Paul Barton of PBS thought sound was better with single wire, he would save money on extra terminals and internal crossover and design his flagship speaker, Stratus Gold-i with single terminals. BTW, I think you just voided the warranty on your Gold-i. I would be interested if you would e-mail Paul at PSB to get his opinion on your modifacation.....
With all due respect to you, Megasam, Martin DeWulf also points out in his article, (and I tend to think he's correct) that in most cases, the speaker manufacturers have jumped on the whole bi-amp bandwagon/hysteria solely because they felt they had to, lest they be perceived as being behind the times---hence, diminished sales. BTW, when I get a chance, I will in fact contact Paul Barton and post and/or email you as to the result.
I always thought that the two sets of terminals, one set for LF and one set for HF were there for bi-amping.
Thanks everyone for your responses. I've gotten some good suggestions. But is it better to have longer speaker wire/shorter interconnects or the other way around? Thanks. Bazmataz Bazmataz@hotmail.com
