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?

First scenario:
Midrange and tweeter fuses blow on the left speaker with Classe CA-200 at moderate - high volumes. Fuse did NOT protect tweeter. I suspsected the amp passed DC.

Second scenario:

This one was the fault of the previous owner who put the incorrect value fuse in for the tweeter. At medium volume levels the tweeter is blown in the right speaker using a McCormack amp, and of course the fuse did not blow. BUT, the volume was low enough that the tweeter should not have been damaged even if the fuse had been by-passed.

So wh at is inconsistent here are the following:

Playback level
amplifiers
distinct speaker
fuses

What IS consistent is the speaker cable. Hence my query.

BTW, the tube amp was a Music Reference RM-9, not nearly enough power. But the two SS amps should have been adequate if not ideal. I do have a pair of McCoramck DNA-1 monoblocks on the way. If 700 watts/channel is not enough for the 3.5s, I am throwing in the towel. But I just wondered if anyone knew the capacitance of the Au24 cables and whether of not this would be an issue.

>Could it be that the ribbon tweeters are more sensitive to inductance/capacitance variances during music than regular tweeters?<

I think that could very well be. At least for now I will have a late 99 pair of 3.5Rs with brand new ribbon tweeters. One more tweeter goes and it's time to re-think this setup....
