DALI Helicon 400 - speaker cable options

I have the MK 1 version and wondering what owners of the speakers are using for their speaker cables and whether they are biwiring them or not. So far have tried JPS Superconductor + biwire and Acoustic Zen Hologram 2 single wire with jumpers. Preferred the latter and it makes me also wonder about the merits of biwiring these speakers vs. good single wire and jumpers. Thanks in advance for your thoughts
