any benefit in a double bi-wire of 8TC?

Talking with Kimber Kable they told me the best sonically sounding version 8TC speaker cable is the internal bi-wire version. They got into technical detail and says the coherent signal path is created equal which perfectly matches the impedence.

The 8TC bi-wires are nice and do clean up some of the sound. However, at the retail price it is painful...
I sold my 8's, kept my single wire 4TC's and spent the couple hundred difference on music.

You might even try a double-bi-wire set of 4TC. For some reason, 4TC sounds completely different (WAY better) than 8TC in my set-up.

In case you want to know, I'm using a NAD 304 integrated and Triangle Zerius 202 speakers.

...And a single-run of 4TC (bi-wiring, while necessary with my B&Ws, doesn't seem to make a difference with the Triangles).

Good luck!
