Yes, 4S11 is a very good speaker cable, I also admit that when I look at high end mass produced speaker cables I look to see if their size matches a 4S11 with a sleeve.
Vandy's really like unterminated cable on their terminal strips but be very careful, use a magnifying glass with a bright light to make sure there are no stray strands...
Do some research or contact Belles Virtuoso about what is required for load being sent out to speaker. My amp could care less about capacitance and needs inductance and resistance to be low, yours could be quite the opposite.
