Cardas vs. Harmonic Technology

I am looking to replace the MIT speaker cable between my Audio research VT200 and my new Magnepan 3.7 speakers. Has anyone compared the Cardas Golden Reference cables to the Harmonic Technology Pro 9s? I have the Golden Reference interconnects throughout my system and was leaning that way but have not had the opportunity to audition the HT Pro 9s. I also use an ARC Ref 3, an Einstein Turntable Choice phono section (SE), and a VPI Classic with a Benz Micro Gullwing.

Thanks in advance.
