Audience Au24 with high current SS amps....

..is anyone using the Au24 speaker cables with high current SS amps? I had good results with these cables with my tube amp, but with two different SS amps of relatively high current I have blown two ribbon tweeters in magnepans. And yes, it was the tweeter in either speaker, not the same one twice. I heard some rumblings that the capacitance of these cables might not be the best match for my application. I cannot find any figures on the Audience website about the inductance or capacitance of their cables. Any thoughts?
