Danacables Sapphire Mk 2 Speaker Cables

Interested in these cables, appreciate any opinions from owners or those who have demo’d a pair. They would be used with Simaudio 700i integrated and Focal Sopra No.2 speakers. 

Thanks in in advance for all responses.
Never heard of these....why not stay with proven brands?
Usually do, but looked at their website and different approach/technology behind their cables. Sounds interesting enough just wondering what others may have experienced.
