Hasse,
I've owned the Argent and 12am and used them in biwire configuration for about 6 yrs. I only recently removed the 12am. Trying not to sound like a sales pitch, I added a virtual dynamics p3 cord to my transport and amp, and my system became too dynmaic to biwire. They sounded much more coherent without biwiring.
Also, after adding the powercords, as mentioned before, the difference in sound quality and characteristics between Argent and 12am became more apparent where having the 12am degraded the system's sound.
