Biwiring: can you really hear the difference?

Markanetz is on the money - use a set of spades and a set of bananas on a single terminal to enable the use of two runs of wire per speaker. Make sure the "better" cable is running to the high driver, not the woofer. This works better - perhaps some of the more enlightened of the 'goners could explain why.

I'm not sure I agree with your premise that biwiring with a neutral sounding cable makes less difference. I have biwired three separate systems in the past couple of years, all using different cable (though all more or less neutral) and it never failed to make a vast improvement. But...you are ALWAYS right to audition before comitting if possible.

A good way to start would be to get borrow a pair of speaker cables that are terminated differently from what you have now. As long as it is decent cable it doesn't have to match what you have too closely. Try them out for a few days, then switch top and bottom. Try that for a few days, then go back to your original single run. Then see what you think.

As for Dopogue's experience - system synergy is a funny thing, and it is very possible that his system liked the Mapleshade cable better than the Kimber. Naim is another brand of gear than comes to mind when talking about funny preferences of cable. I do wonder what would happen with a biwired setup of the Mapleshade cables?

I agree whatever you do it will be audition. Double runs will sound differently than a single bi-wire cable, or a single run with jumpers, etc.

Dopogue:

Well, in that case then I guess I wouldn't argue either. Though I might try it anyway just to see:)

To test system compatibilty, I suggest getting some cheap radio shack speaker cable in, say, 12 ga. and 10 ga., then you can explore the the differences of more, fatter wire and actually biwiring. The effect of gauge can have as much of an effect as the separete termination, and the type or quality of termination could have as much an effect as a separate termination. I suggest this as a cheap way to find out while controlling the experiments. And then, If you use this wire, you have a reference to start with to get real wire, as EVERYBODY knows what it sounds like.
