Cabling ideas for Meadowlark Kestrals?

I am using Nordost blue heaven and they work pretty well. Since these are biwired and a 4 meter run in a second system I am a little constrained on my choices for $ reasons. I saw a pair of shotgunned Nirvans on the site the other day and they would be very very good especialy for tubes. For the $ the Blue Heaven work well.

The most logical choice would be DH Labs. These speakers are internally wired with them.

I'm using Zu Cable Julians... www.zucable.com. These replaced Harmonic Tech Pro-11
