Expensive wire VS. less expensive biwire

I've been biwiring for about 8 years now and I like the effect it had when I originally tried it. The cables I'm using are Tara Labs Quantum Reference. 2 pair of 8 foot runs cost about $225 each (retail). I've been thinking of trying to upgrade my speaker cable and I'm struggling with the biwire issue again. Looking at used cable with a budget of about $600 total, do you think there's more to gain running a single $600 cable or two $300 cables. Like I said I like the way biwire sounds, but I've never really listened to a single wire that cost twice as much in my system.
Jmc; this is a potentially "explosive" thread. That said, Richard Vandersteen states in the owner's manuals of his 2Ce and 3A speakers that a bi-wired run of moderately priced wire will typically out-perform a single run of more expensive cable. I've followed RV's advice with good results, but I think it depends on speakers and maybe amps. I like to stick to manufactures recommendations, or at least start with them. BTW, I use Syn. Res. Sig. #2 (mod. priced) in bi-wired runs to Vand. 3As. Good Luck. Craig.
Dont be fooled by the BIwire claims.its just a bunch of hype to sell wire.Buy the wire that sounds best to you then use a 6 Inch length of same wire and jumper them.Even better have the speakers converted to single wire.
Try to borrow some cables and try it yourself. It is the only way to really tell. A lot of what works in this hobby are system and or speaker dependent. I have B+W speakers and found a very noticeable improvement bi-wiring. There is another thread on upgrading jumpers on bi-wire speakers currently running. If Bi-Wiring did not work, neither would better jumpers, but new jumpers seem to work in some systems

There is no such thing as does not work IMHO. Thomas Edison tried over 5000 times before he got the light bulb to work. We consider him a genius, but he only had one success and over 5000 failures. Most people would have given up after one or two tries and proclaimed it impossible or unworkable.

The question of bi-wire is very system dependent. Some speakers beg for bi-wire, while others have it as an option (marketing), but it does very little for the speaker. It also depends on the amp. Very powerful and high current amplifiers tend to have less benefit when bi-wired. Still the speaker is the most important.

You obviously have a few options, but first is to determine what you like or don't like about your current cable. Is it good bass articulation, is it bright--I don't know I have never owned Tara cables. It may be, that this cable could be 1/2 of your bi-wire solution. Perhaps, it becomes the bass cable and you purchase another cable for the top end. Most people would recommend that in that case you stick with Tara and buy a higher end model for the high end. I don't necessarily subscribe to that--unless you can't listen before you buy--then it's definitely safer. You do need to stick to the same length runs of course. 8 feet is pretty standard and I would do as Sugarbrie suggested and get some from the Cable Co. They have a very extensive lending library and they are also very helpful with these sorts of issues.
My old Infinity Reference IIa's have 5 way speakers, so I rewired my system to have FIVE WAY wiring, using a double set of AQ Midnight I made use of the 24 individual wires and have a much better sounding system (on the crossover end I used (24? pin) gold pin computer connectors)
Hello, I have Vandersteens 2ce sigs and I am using mapleshade speaker cable with their jumper. I auditioned biwire cable from the cable co. and found that the performance of mapleshade was better. My budget with the cable co. was 1500.00 and I think mapleshade was 300.00 and don't quote me on that. I think it is of the utmost importance to audition and find out what sounds best in your system.
