Bi-wire using single or two cables?

I agree with Sugarbrie. If I were in your shoes I'd definitely go for the better single run first, then decide later whether or not an upgrade to biwire is necessary.

Before recommending a cable other than Audioquest, I'd need to know a few things first: What are the sound characteristics of your system? Are you trying to change the way something sounds? What length of speaker cable do you think you'll need?

Without that information my best stab would be to suggest DH Labs Silversonic T-14. A good bargain in a silver wire. This cable doesn't cost a fortune and will add spark to lifeless systems. Another step up is the Analysis Plus Oval Nine. This cable is about $347 new for an 8 foot single run pair with spades. You can find these used here for under $250. The APs are much fuller sounding than the T-14s and have better soundstaging.

I hope I've helped in some way. Have fun and happy hunting!

Thanks Ewha. Now I have a better picture.

From your description and concerns, I don't think the DH Labs are what you're looking for. In my system they were at times strident and had a flat, in-your-face presentation.

I totally forgot to suggest the baby brother to the Analysis Plus Oval Nine. The Oval 12. I own the AP9s, and from what I've read here people think the AP12s are close in sound to the AP9s at much less cost. Here's a link to the AP12s:

The Analysis Plus copper cables are warm, yet detailed. They managed to tame a lot of the hot spots in my setup, and at the same time introduced a very wide and deep soundstage which I was lacking.

Let me know if you have any other questions.
