Bi-Wiring my Vandersteen 3A with Kimber Kable

I have 2 different types of the Kimber Kable - the 4 PR and the 4 TC. When I am doing the Bi - Wiring should I have the PR or the TC connected to the woofer? I have a NAD 2100 Power Amp and a NAD pre-amp. Right now, I have the PR connected to the lower terminals, and the TC to the upper, but I thinking that the TC is a better cable, perhaps that cable should go to the bass? Thanks for the help.

I'd listen both ways and decide for yourself. IMO, the 4TC should go to the high freq. and the PR to the low freq. Midrange is most crucial and that's why I'd prefer the better cable going there. Bill
