Harmonic Tec vs Dh labs Q 10 vs TMC Gold reference

I am currently in the process of changing my kimber 8tc biwired speaker cable on the B&W nautilus 804 speakers. I need a cable that is not as forward as the kimbers.The HT Pro 9 biwired, DH Labs Q10 biwired, and the TMC Golden Reference Biwired I picked were based on the feedback left by various consumers in audioreview site and what most of them have on their B&W nautilus 804 speakers. I am asking your opinion as to what cable I should consider of the three or other speaker cable that you see would work better. I tend to like the sound of the Cardas Cables. Speaker cable should be less than $700 use.

My equipment
Parasound Pre-2500
Parasound Amp-2205
Cd Player Arcam 72
Revel B15 sub
Cardas cross power cords on amp, cd player, and pre-amp
Tara Labs Prime generation II between cd and pre-amp
TMC ic between Pre-Amp and Amp

Thanks
