Need Speaker Cable advice


I have Martin Logan SL2's and a logos as my front channels in my home theater. I am adding a parasound 2003a to drive them. I would like to buy used speaker cables in the 300-400 dollar range. i don't know anything about speaker cables. any advice?

Sorry Tm12, but I borrowed an absurdly long (20 ft.) run of Nordost SPM speaker cable from a dealer and it simply, utterly, and thoroughly trounced the 6 ft. JPS speaker cable then IN MY SYSTEM. The capitialization refers to the fact that this was done by direct comparison at my home. This is not a snipe at Tm12, I've never listened to any Audioquest or DH cables. I just don't agree with his view that Nordost has obtained its reputation on the basis of hype. Is the Nordost overpriced? I don't know how much it costs them to make their cable, although I have heard from one high end manufacturer that it really isn't all that expensive to make. Then again, neither he not I make cable for a living, so who knows? Almost all cable is overpriced in the sense that you can get almost any cable you're interested in at sites like Audiogon, generally for 1/2 list price. I think Tm12 and I agree that you should never buy cable new if you can avoid it (if you have specific needs for a cable with an odd sized length, you may be forced to buy it new). The bottom line Kkirkpa@aol.com is that you should try to borrow cable over a weekend from a dealer and determine with your ears, in your listening room, with your gear, if the cable sounds good. And don't be biased against Nordost; in my system it sounds better than anything else I've compared it to.
Whoops, the above advice was for Wetpetinc@msn.com, not Kkirkpa@aol.com. Sorry for the error, Cardinal
Based on the amount of parallel conductor you get for the money, the Nordost speaker cables are the most expensive. But, if you've compared them with everything else, and like them better, then that's fine with me.
I would also suggest auditioning Transparent Cables - probably the "Super" grade. These cables make a difference. Let your ears be your guide.
