Not a formal review, since I'm using this wire in a bi-amp system:
As part of my recent bi-amp setup, I decided to finalize the wire selection. For the bass panel of the Magnepan 1.6QRs, I went with a pair of Kimber 8PR speaker wire. This classic can pass enough current to handle the big power of the Threshold amplifier. For the treble section, I went with a used pair of Cardas Hexlink 5-C wire via Audiogon. At one time Hexlink was the top of the Cardas line.
As usual, I wasn't expecting much difference with changing speaker wires, but I sure was surprised. The Hexlink has a big sound - warm and almost golden - that lets the music breathe with ease and power. I certainly wouldn't call it uber-detailed or very transparent - but it sure is musical and very enjoyable for long-term listening sessions. As usual, the Kimber did a great job with the bass - sound very detailed, speedy, and with no overhang.
I just love it when a system comes together.
