Light weight speaker cables

L.S., 

With your feedback, I installed my NAD system. Recently, I exchanged the NAD M2 (already a decade old) for a more recent NAD M32. I have Inakustik LS-1620 Reference speaker cables... but they're really heavy. Maybe too heavy as all their weight is hanging on the posts. The M2 could deal with it, but the M32 weighs less.

So I'm looking for light weight speaker cables (I prefer available in biwire). I've seen the Nordost collection, but that seems like a risk with kids and a cat. I've seen the latest Inakustik AIR cables.  
Which other options do I have?

Thanks,
Koen
